Synthesis and property of alkyl dioxyethyl α-D-xyloside was written by Wu, Xiubing;Kuang, Na;Chen, Langqiu;Fan, Yulin;Fu, Fang;Li, Jiping;Zhang, Jing. And the article was included in Journal of Molecular Liquids in 2020.Synthetic Route of C10H22O3 The following contents are mentioned in the article:

Due to the inherent defects of the long alkyl chain in the related hydrophilicity and water solubility, alkyl α-D-xylosides (7) had hardly the practical application as sugar-based surfactants and should be reconstructed to obtain alkyl dioxyethyl α-D-xylosides (5) with dioxyethylene fragment (-(OCH₂CH₂)_2-) as the hydrophilic spacer to increase the related TPSA value. With D-xylose as the raw material, 1,2-cis alkyl dioxyethyl α-D-xylosides (5a-5f, n = 6-12) were stereoselectively synthesized. Their physicochem. properties including water solubility, surface tension, foamability, emulsification, thermotropic liquid crystal, and hygroscopicity had been investigated. Their water solubility was found to decrease gradually whereas their calculated HLB numbers were 14.72 → 11.67 (n = 6 → 12) with increasing alkyl chain length (n). Dodecyl dioxyethyl α-D-xyloside (5f) had not water solubility because the HLB number was low. Furthermore, their CMC values decreased with increasing the alkyl chain length, and the CMC value of decyl dioxyethyl α-D-xyloside (5e) was as low as 9.21 x 10^-5 mol·L^-1. Octyl dioxyethyl α-D-xyloside (5c) had the lowest surface tension (27.25 mN·m^-1) at the CMC. Both of nonyl and decyl dioxyethyl α-D-xylosides (5d & 5e) possessed good foaming power and foam stability. Decyl dioxyethyl α-D-xyloside (5e) had the strongest emulsifying property either in the toluene/water system or in the octane/water system. Nonyl dioxyethyl α-D-xylosides (5d) had the most stylish SA texture. Hexyl dioxyethyl α-D-xyloside (5a) possessed the strongest hygroscopicity. Therefore, the alkyl dioxyethyl α-D-xylosides as a class of novel sugar-based surfactants will be widely considered as promising candidates for various practical applications. This study involved multiple reactions and reactants, such as 2-(2-(Hexyloxy)ethoxy)ethanol (cas: 112-59-4Synthetic Route of C10H22O3).

2-(2-(Hexyloxy)ethoxy)ethanol (cas: 112-59-4) belongs to ethers. Esters perform as high-grade solvents for a broad array of plastics, plasticizers, resins, and lacquers, and are one of the largest classes of synthetic lubricants on the commercial market. Polyesters are important plastics, with monomers linked by ester moieties. Esters contain a carbonyl center, which gives rise to 120° C–C–O and O–C–O angles. Unlike amides, esters are structurally flexible functional groups because rotation about the C–O–C bonds has a low barrier. Their flexibility and low polarity is manifested in their physical properties; they tend to be less rigid (lower melting point) and more volatile (lower boiling point) than the corresponding amides.

Developing consensus on content and format of e-portfolio for MHPE students: A Delphi study. was written by Ansar, Ambreen;Yasmeen, Rahila;Rizvi, Robina Mushtaq. And the article was included in JPMA. The Journal of the Pakistan Medical Association in 2022.HPLC of Formula: 2380-78-1 The following contents are mentioned in the article:

OBJECTIVE: To build a consensus on portfolio framework for master’s in health professional education students and document programme learning outcomes, tasks for students related to each outcome, and the pieces of evidence regarding the completion of each task. METHODS: The modified Delphi study was conducted from February to July 2020 at Riphah International University, Islamabad, Pakistan, and comprised a three-round electronic-based survey of faculty members associated with the master’s in health professional education programme, alumni, and current students as well as portfolio experts. The panellists had to choose from 10 programme learning outcomes, 75 tasks for students to achieve those outcomes, and 510 pieces of evidence to confirm that the tasks had been done to achieve the outcomes. A consensus cut-off of ≥80% was decided to select the item. RESULTS: Of the 45 stakeholders approached, 41(91.5%) responded in round 1. Of them, 31(75.6%) responded in round 2, while round 3 comprised responses from 31(96.7%) subjects. The draft template was originally derived from the master’s in health professional education programme guide, expert opinions, and systematic literature review available for portfolios of other higher education degrees. The list of items was refined through a pilot study. The final template was approved by the expert panel after 3 iterations. The final list of items included 59 (78.6%) tasks and 105(21%) pieces of evidence related to all the 10 programme learning outcomes. CONCLUSIONS: The important programme learning outcomes, their related tasks, and the required pieces of evidence to be added in the e-portfolio of master’s in health professional education programme students were identified, and recommendations for the format of implementation and assessment were given. This study involved multiple reactions and reactants, such as 4-Hydroxy-3-methoxyphenethanol (cas: 2380-78-1HPLC of Formula: 2380-78-1).

4-Hydroxy-3-methoxyphenethanol (cas: 2380-78-1) belongs to ethers. Esters are also usually derived from carboxylic acids. It may also be obtained by reaction of acid anhydride or acid halides with alcohols or by the reaction of salts of carboxylic acids with alkyl halides. Esters are more polar than ethers but less polar than alcohols. They participate in hydrogen bonds as hydrogen-bond acceptors, but cannot act as hydrogen-bond donors, unlike their parent alcohols. This ability to participate in hydrogen bonding confers some water-solubility.HPLC of Formula: 2380-78-1

Volatility by Design. Synthesis and Characterization of Polyether Adducts of Bis(1,1,1,5,5,5-hexafluoro-2,4-pentanedionato)barium and Their Implementation as Metal-Organic Chemical Vapor Deposition Precursors was written by Belot, John A.;Neumayer, Deborah A.;Reedy, Charles J.;Studebaker, Daniel B.;Hinds, Bruce J.;Stern, Charlotte L.;Marks, Tobin J..

The synthesis and characterization of polyethers and volatile, low-melting polyether complexes of bis(1,1,1,5,5,5-hexafluoro-2,4-pentanedionato)barium Ba(hfa)₂·RO(CH₂CH₂O)_nR’ where R = R’ = Me, n = 3; R = Me, R’ = Et, n = 3; R = R’ = H, n = 5, 6; R = R’ = Me, n = 4; R = Me, R’ = Et, n = 5; R = Me, R’ = Bu, n = 5, 6; R = Me, R = C₅H₁₁O, n = 3; R = Me, R’ = n-C₆H₁₃, n = 4, 5; R = Et, R’ = Bu, n = 5; R = Bu, R’ = Bu, n = 4, 6; R = Bu, R’ = n-C₆H₁₃, n = 5 are reported. The complexes are conveniently synthesized by reaction of n-propylammonium⁺hfa^– in DMF with an aqueous solution of Ba(NO₃)₂ and the polyether or, alternatively, by reaction of the polyether with Ba(hfa)₂ in toluene. These new complexes were characterized by elemental anal., FTIR, ¹H, ¹³C, and ¹⁹F NMR, MS, x-ray diffraction (Ba(hfa)₂·CH₃O(CH₂CH₂O)₃CH₃·H₂O, Ba(hfa)₂·CH₃O(CH₂CH₂O)₅C₂H₅), and TGA. The m.ps. of the complexes are strongly dependent on the architecture of the polyether chain and dimensions of the terminal polyether substituent, with the lowest m.ps. corresponding to the longest polyethers having the largest terminal groups. The volatility of the Ba(hfa)₂·polyether compounds is dependent on mol. weight and mol. structure; however, there is little direct correlation between m.p. depression and enhanced volatility. The applicability of these complexes in metal-organic CVD is demonstrated by the successful growth of phase-pure BaTiO₃ thin films using Ba(hfa)₂·CH₃O(CH₂CH₂O)₅C₂H₅ as the Ba source. Phase composition and epitaxy in these films is analyzed by energy-dispersive x-ray spectroscopy and x-ray diffraction Θ-2Θ, ω, and φ scans. This study involved multiple reactions and reactants, such as 2-(2-(Hexyloxy)ethoxy)ethanol (cas: 112-59-4Recommanded Product: 112-59-4).

2-(2-(Hexyloxy)ethoxy)ethanol (cas: 112-59-4) belongs to ethers. Volatile esters with characteristic odours are used in synthetic flavours, perfumes, and cosmetics. Certain volatile esters are used as solvents for lacquers, paints, and varnishes. Cyclic esters are called lactones, regardless of whether they are derived from an organic or inorganic acid.

Identification and quantification of lignin monomers and oligomers from reductive catalytic fractionation of pine wood with GC x GC – FID/MS was written by Dao Thi, Hang;Van Aelst, Korneel;Van den Bosch, Sander;Katahira, Rui;Beckham, Gregg T.;Sels, Bert F.;Van Geem, Kevin M..

Thorough lignin characterization is vital to understand the physicochem. properties of lignin and to evaluate lignocellulose biorefinery processes. In this study, an in-depth characterization of lignin oil, obtained from reductive catalytic fractionation (RCF) of pine wood, was performed with quant. GC x GC – FID anal. and qual. GC x GC – MS. By utilizing high-temperature resistant column sets in the GC x GC system and by applying a derivatization step, unambiguous detection of lignin monomers, dimers, and trimers is enabled. In addition to confirm the identity of eleven monomers, corresponding to 34 wt% of the RCF lignin oil, thirty-six dimers (16 wt%) and twenty-one trimers (7 wt%) were comprehensively identified by anal. of their mass spectra and quantified by a FID, encompassing the identity of an addnl. 23 wt% of the RCF lignin oil. The proposed structures reveal the interlinkages present in the dimeric and trimeric oligomers, containing β-5, β-1, β-β, 5-5, and a minor fraction of β-O-4 and 4-O-5 bonds. Furthermore, aliphatic end-units in the dimeric and trimeric mols. were identified, consisting of various substituents at the C4 position, that have been previously observed in the RCF-derived lignin monomers. To reduce complexity for anal., the RCF oil was separated into six fractions, prior to anal. The structural motifs (inter-unit linkages and end-units) that are found in the different fractions vary significantly, such that the lignin fractions extracted in more polar solvents contained higher mol. weight fragments and more hydroxyl containing structural motifs. The identified structures of individual dimer and trimer mols. by GC x GC align well with and further complement the recent findings from ¹H-¹³C HSQC NMR spectroscopy, demonstrating complementarity between both 2D techniques to obtain a holistic view on both the mol. structures and the distribution of bonds and end-units in RCF oil. The combination of these two techniques provides a powerful tool for future RCF and other lignin depolymerization research.

Black pepper prevents anemia of inflammation by inhibiting hepcidin over-expression through BMP6-SMAD1/ IL6-STAT3 signaling pathway was written by Banerjee, Somesh;Katiyar, Parul;Kumar, Lokesh;Kumar, Vijay;Saini, Shashank Sagar;Krishnan, Vengadesan;Sircar, Debabrata;Roy, Partha. And the article was included in Free Radical Biology & Medicine in 2021.Electric Literature of C9H12O3 The following contents are mentioned in the article:

Hepcidin, a circulatory hepatic peptide hormone, is associated with systemic iron homeostasis. Inflammation leads to an increase in hepcidin expression, which dysregulates body iron level. The related disorder, anemia of inflammation, is the second most prevalent anemia-related disorder worldwide. In the present study, we conducted in vitro and in vivo studies to evaluate the effect of black pepper (BP) and its major bioactive alkaloid, piperine, on anemia of inflammation. The initial in vitro study using human hepatocyte cell line, HepG2, confirmed that among different black pepper extracts: methanol (BPME), ethanol (BPEE) and aqueous (BPAE), BPME to be most effective in downregulating transcription of hepcidin gene. Further, BPME and piperine significantly downregulated hepcidin protein expression at 200μg/mL and 100μM concentrations, resp. In the next phase, BPME and piperine were found to significantly attenuate BMP-6 and IL-6 induced hepcidin overexpression by downregulating the increased level of pSMAD1 and pSTAT3 proteins, resp. For in vivo study, we first s.c. injected male BALB/c mice with oil of turpentine, thrice within a period of two weeks, in order to enhance the expression of hepcidin. After that, the i.p. administration of BPME and piperine at 70 and 25 mg/kg body weight, resp., on alternate days for a period of another two weeks resulted in downregulation of hepcidin overexpression in diseased mice, as confirmed by RT-PCR and immunoblot anal. The histopathol. of liver tissue confirmed increased iron bioavailability in BPME and piperine treated animals. The mol. docking-based interaction studies demonstrated the binding potential of piperine with SMAD1 and STAT3 proteins. The binding patterns supported the proposed inhibition of hepcidin activating proteins. All together, these findings suggest black pepper as a therapeutic candidate for the treatment of anemia of inflammation.

4-Hydroxy-3-methoxyphenethanol (cas: 2380-78-1) belongs to ethers. Volatile esters with characteristic odours are used in synthetic flavours, perfumes, and cosmetics. Certain volatile esters are used as solvents for lacquers, paints, and varnishes. Many esters have the potential for conformational isomerism, but they tend to adopt an s-cis (or Z) conformation rather than the s-trans (or E) alternative, due to a combination of hyperconjugation and dipole minimization effects. The preference for the Z conformation is influenced by the nature of the substituents and solvent, if present. Lactones with small rings are restricted to the s-trans (i.e. E) conformation due to their cyclic structure.Electric Literature of C9H12O3

Effect of Molecular Structure on Wetting Behavior at the Air-Liquid Interface of Water + Alcohol Mixtures was written by Yeh, Ming-Chih;Lin, Ping-Chang;Chen, Li-Jen. And the article was included in Journal of Physical Chemistry B in 2004.Synthetic Route of C10H22O3 The following contents are mentioned in the article:

In this study, the wetting behavior of binary water + alc. mixtures was carefully investigated by using eight different short-chain alcs. These binary mixtures exhibit liquid-liquid equilibrium over the exptl. temperature range 10∼40 °C. The wetting behavior of the upper liquid (alc.-rich) phase at the surface of the lower liquid (aqueous) phase can be determined according to the wetting coefficient resulting from the interfacial tension measurements. Mol. structure of alcs. plays an essential role in the wetting behavior. The purpose of this study is threefold. (1) The effect of the hydrocarbon chain length of alcs. was examined by employing water + 1-butanol (C₄E₀), water + 1-pentanol (C₅E₀), and water + 1-hexanol (C₆E₀) three systems, where C_iE_j is the abbreviation of a nonionic polyoxyethylene alc. C_iH_2i+1(OCH₂CH₂)_jOH. The shorter chain alc. has a stronger tendency to wet the surface of the aqueous phase. (2) The effect of number of oxyethylene groups of alcs. was investigated by using three mixtures, water + C₆E₀, water + C₆E₁, and water + C₆E₂. An interfacial phase transition from partial wetting to nonwetting was observed for water + C₆E_j mixtures as the number of oxyethylene groups j increases from 1 to 2. (3) The effect of isomeric structures of alcs. on wetting behavior was investigated by studying three mixtures, water + 1-pentanol, water + 2-pentanol (2-C₅E₀), and water + tert-pentanol (t-C₅E₀). An interfacial phase transition from partial wetting to complete wetting occurs while the mol. structure of alcs. evolves from linear (C₅E₀) to near spherical (t-C₅E₀) shape. This study involved multiple reactions and reactants, such as 2-(2-(Hexyloxy)ethoxy)ethanol (cas: 112-59-4Synthetic Route of C10H22O3).

Metabolomics reveals diet-derived plant polyphenols accumulate in physiological bone was written by Alldritt, Isabelle;Whitham-Agut, Beatrice;Sipin, Miguel;Studholme, Jacob;Trentacoste, Angela;Tripp, Jennifer A.;Cappai, Maria Grazia;Ditchfield, Peter;Deviese, Thibaut;Hedges, Robert E. M.;McCullagh, James S. O.. And the article was included in Scientific Reports in 2019.SDS of cas: 2380-78-1 The following contents are mentioned in the article:

Plant-derived secondary metabolites consumed in the diet, especially polyphenolic compounds, are known to have a range of pos. health effects. They are present in circulation after ingestion and absorption and can be sequestered into cells within particular organs, but have rarely been investigated systematically in osteol. tissues. However, a small number of polyphenols and similar mols. are known to bind to bone. For example alizarin, a plant derived anthraquinone and tetracycline (a naturally occurring antibiotic), are both absorbed into bone from circulation during bone formation and are used to monitor mineralization in osteol. studies. Both mols. have also been identified serendipitously in archaeol. human bones derived from natural sources in the diet. Whether an analogus mechanism of sequestration extends to addnl. diet-derived plant-polyphenols has not previously been systematically studied. We investigated whether a range of diet-derived polyphenol-like compounds bind to bone using untargeted metabolomics applied to the anal. of bone extracts from pigs fed an acorn-based diet. We analyzed the diet which was rich in ellagitannins, extracts from the pig bones and surrounding tissue, post-mortem. We found direct evidence of multiple polyphenolic compounds in these extracts and matched them to the diet. We also showed that these compounds were present in the bone but not surrounding tissues. We also provide data showing that a range of polyphenolic compounds bind to hydroxyapatite in vitro. The evidence for polyphenol sequestration into physiol. bone, and the range and specificity of polyphenols in human and animal diets, raises intriguing questions about potential effects on bone formation and bone health. Further studies are needed to determine the stability of the sequestered mols. post-mortem but there is also potential for (palaeo)dietary reconstruction and forensic applications.

Converting lignin to value added products at high yields provides an avenue for making ethanol biorefineries more profitable while reducing the carbon footprint of products generally derived from petroleum. In this study, corn stover lignin was depolymerized by catalytic transfer hydrogenolysis (CTH) in supercritical ethanol with a Ru/C catalyst. The lignin derived bio-oil was then sequentially extracted utilizing hexane, petroleum ether, chloroform and Et acetate as solvents in order of less polar to polar and the subsequent bio-oils were characterized using GPC, GC/MS and HSQC NMR. Results show lignin derived compounds were sequentially extracted into groups depending on the solvent polarity. Antimicrobial properties of the bio-oils were screened against Gram-pos. (Bacillus subtilis, Lactobacillus amylovorus, and Staphylococcus epidermidis), Gram-neg. (Escherichia coli) bacteria and yeast (Saccharomyces cerevisiae) by examining microbial growth inhibition. Results show that CTH derived bio-oils inhibited all tested organisms at concentrations less than 3 mg/mL. Total monomer concentration and the presence of specific monomers (i.e., syringyl propane) showed correlations to antimicrobial activity, likely due to cell death or membrane damage. This study provides insights into using sequential extraction to fractionate lignin-derived compounds and correlations between the properties of the extracted compounds and their antimicrobial activity. A lignin-based bio-oil was prepared from catalytic transfer hydrogenolysis of purified corn stover lignin with ethanol and a ruthenium on carbon catalyst. Polar and nonpolar solvents were used to sequentially extract different compounds The raw bio-oil and sequential extraction fractions exhibited antimicrobial properties against Gram-pos./neg. bacteria and yeast, with activity related to total monomer content and specific monomers.

In an effort to develop water-soluble singlet-oxygen (¹O₂) photosensitizer, we synthesized a series of phosphorus porphyrin complexes (1, (RO)₂P(tpp)⁺Cl^–, tpp = tetraphenylporphyrinato ligand, R = -(CH₂CH₂O)_m-(CH₂)_n-H, m = 0-3, n = 1, 2, 4, 6) and evaluated their performance characteristics. Water-solubilities of 1 (m = 1, 2 and n = 1, 2, 4, 6) were determined to be >1.0 mM, which was higher than the parent (HO)₂P(tpp)⁺Cl^–. The quantum yields for the generation of ¹O₂ in water based on the amount of ¹ 1* were determined to be 0.73, 0.69, and 0.62 for 1d (m = 2, n = 4), 1e (m = 2, n = 2), and 1f (m = 2, n = 1), resp. Photo-inactivation by 1 was performed with yeast (Saccharomyces cerevisiae), and was evaluated using a inactivation factor A _F = ([1]_M × T _1/2)^-1, where [1]_M is the min. effective concentration of 1 and T _1/2 is a half-life of the yeast initially used. In the case of 1b (m = 1, n = 6) and 1c (m = 2, n = 6), [1]_M was determined to be 5 nM in the photo-sterilization. Bio-affinity was evaluated by the adsorbed concentration of 1 ([P]_ad) into the yeast, which was measured by absorption spectrophotometry using a confocal laser-scanning microscope. These findings revealed that a large amount of 1 was adsorbed into the yeast. The estimated amount of 1b obtained from 10 μM aqueous solution came to 171 mM (17,100 fold) in terms of concentration As an increase in carbon number (n) of the alkyl group on axial ligands, A _F and [P]_ad increased. It is strongly suggested that the photo-inactivation took place with the assistance of the attack of ¹O₂ inside the cells.

Hydroxyl Group Stabilization for Increased Yields of Low-Molecular-Weight Products in the Copyrolysis of Cellulose and Thermoplastics was written by Nallar, Melisa;Wong, Hsi-Wu. And the article was included in Industrial & Engineering Chemistry Research in 2019.Name: 2-(2-(Hexyloxy)ethoxy)ethanol The following contents are mentioned in the article:

Biomass is a promising renewable and sustainable resource to produce energy and value-added chems. Fast pyrolysis is one of the simplest thermochem. methods to convert biomass into high yields of liquid products that can be upgraded into drop-in fuels or platform chems.; however, its diverse product distributions and low product selectivity incur significant cost due to subsequent upgrading and separation operations. In this work, a strategy to promote yields of low-mol.-weight products (LMWPs) from cellulose pyrolysis via hydroxyl group stabilization using molten polymers (MPs) is presented. Three types of thermoplastics, high-d. polyethylene (HDPE), polyethylene glycol (PEG), and polystyrene (PS), were copyrolyzed with cellulose to investigate the possible hydroxyl group stabilization effects caused by the ether and aromatic moieties in MPs during cellulose pyrolysis. A custom-made batch pyrolysis reactor was employed for the copyrolysis experiments Our results showed that the combined yields of levoglucosan (LG) and LMWPs significantly increased in the presence of MPs due to the phys. inhibition of anhydrosugar oligomer evaporation The product distributions were varied dependent on the MPs used. In particular, both ether groups in PEG and aromatic groups in PS were found to stabilize the cellulosic hydroxyl groups during glycosidic bond cleavage, inhibiting the formation of LG. Aromatic moieties in MPs were observed to create a stronger inhibition effect on the glycosidic bond cleavage than ether moieties. Our experiments also suggest that both ether and aromatic groups in MPs stabilize the hydroxyl groups during dehydration, leading to increased yields of products from retro-Diels-Alder fragmentation. Ether moieties were found to be more effective at inhibiting dehydration than aromatic moieties. Yields of the HDPE-derived products increased during copyrolysis, suggesting a possible catalytic effect in HDPE pyrolysis caused by the LMWPs produced from carbohydrate pyrolysis. Yields of the PEG-derived products increased only in the presence of cellulose and glucose, whereas yields of the PS-derived products were unaffected in all copyrolysis experiments A possible reaction mechanism accounting for the hydroxyl group stabilization effects is proposed based on our exptl. findings. This study involved multiple reactions and reactants, such as 2-(2-(Hexyloxy)ethoxy)ethanol (cas: 112-59-4Name: 2-(2-(Hexyloxy)ethoxy)ethanol).

2-(2-(Hexyloxy)ethoxy)ethanol (cas: 112-59-4) belongs to ethers. Esters are widespread in nature and are widely used in industry. In nature, fats are in general triesters derived from glycerol and fatty acids. Esters are responsible for the aroma of many fruits, including apples, durians, pears, bananas, pineapples, and strawberries. Because of their lack of hydrogen-bond-donating ability, esters do not self-associate. Consequently, esters are more volatile than carboxylic acids of similar molecular weight.Name: 2-(2-(Hexyloxy)ethoxy)ethanol
