Changes in chemical and sensory properties of Amarone wine produced by Penicillium infected grapes was written by Zapparoli, Giacomo;Lorenzini, Marilinda;Tosi, Emanuele;Azzolini, Michela;Slaghenaufi, Davide;Ugliano, Maurizio;Simonato, Barbara. And the article was included in Food Chemistry in 2018.Recommanded Product: 4-Hydroxy-3-methoxyphenethanol The following contents are mentioned in the article:

There is very little information on effects of Penicillium on aroma of passito wine. This study analyzed chem. composition and sensory properties of Amarone wines produced from withered grapes artificially contaminated by P. expansum or P. crustosum. Changes in properties of the two wines were evident by comparing wines obtained from healthy and Botrytis cinerea infected grapes used as controls. Penicillium infection affected primary and volatile composition of Amarone wine. Sensory profiles of these wines, obtained by descriptive anal., resulted in clear differences in the wines between themselves and the control wines. Partial least square regression anal. explained only partially the relationship between mols. and sensory descriptors, and showed the existence of complex interactions of compounds mainly involved in specific aroma attributes. GC-olfactive anal. showed a greater number of odor regions in P. crustosum wine compared to control wines. Useful insight was provided into understanding how Penicillium rotten grapes affect Amarone wine properties. This study involved multiple reactions and reactants, such as 4-Hydroxy-3-methoxyphenethanol (cas: 2380-78-1Recommanded Product: 4-Hydroxy-3-methoxyphenethanol).

4-Hydroxy-3-methoxyphenethanol (cas: 2380-78-1) belongs to ethers. Carboxylic acid esters of low molecular weight are colourless, volatile liquids with pleasant odours, slightly soluble in water. Acyl chlorides and acid anhydrides alcoholysis is another way to produce esters. Acyl chlorides and acid anhydrides react with alcohols to produce esters. Anydrous conditions are recommended since both acyl chlorides and acid anhydrides react with water.Recommanded Product: 4-Hydroxy-3-methoxyphenethanol

Hydrogen sulfide (H₂S) releasing capacity of isothiocyanates from Moringa oleifera Lam was written by Wang, Xiangshe;Liu, Yunjiao;Liu, Xingdi;Lin, Yi;Zheng, Xueqin;Lu, Yuyun. And the article was included in Molecules in 2018.Name: 2-(2-(Hexyloxy)ethoxy)ethanol The following contents are mentioned in the article:

Moringa oleifera Lam. is rich in phytochem. compounds especially glucosinolates (GSs) and isothiocyanates (ITCs), which are active compounds for cancer chemoprevention benefits of Brassicaceae vegetables. In this study, we determined the total contents of GSs and ITCs and their specific profiles in different Moringa tissues including seeds, stems, leaves and roots. Seeds (seeds with shell and seed kernel) showed significantly higher levels of total GSs and ITCs than that of other Moringa tissues. The hydrogen sulfide (H₂S) releasing capacity of total ITCs extracted from different Moringa tissues was determined by lead (II) acetate assay in 24-well plates. The H₂S releasing capacity of different Moringa tissues were evaluated and compared. Moringa seeds showed the highest H2S releasing capacity, followed by roots, leaves and stems. Our results suggest that Moringa based foods may exhibit health benefits due to its GSs and ITCs contents that are the precursors for H₂S, in addition to the recognized action mechanisms of ITCs.

Identification of Bacillus strains producing glycosidases active on rutin and grape glycosidic aroma precursors was written by Haure, Maxime;Chi Nguyen, Thi Kim;Cendres, Aurelie;Perino, Sandrine;Wache, Yves;Licandro, Helene. And the article was included in LWT–Food Science and Technology in 2022.Computed Properties of C9H12O3 The following contents are mentioned in the article:

Most of the glycosidic aroma precursors in grape consist of diglycosides such as rutinoside. Yeast glycosidases have been extensively studied but their activity is limited to monoglucosidic precursors. Yet, there is no study about application of glycosidases active on rutinoside in grape. In this study, we screened Bacillus isolates for their glycosidase activities on rutin and grape aroma precursors. One Bacillus amyloliquefaciens and one Bacillus licheniformis strains produced extracellular glycosidases, active on both rutin and para-nitrophenol-α-L-rhamnoside. The specific rutinosidic activities were 6.2 and 4.1 pkat/mg resp., and supernatants were active on Muscat grape glycosidic aroma precursors. Both strains were able to release monoterpenoids and benzenoids. The most released monoterpenoid in grape pomace was neric acid, with 378μg/kg and the most released benzenoid was 2-phenylethanol, with 189μg/kg for B. licheniformis. These glycosidases are interesting tools to target rutinosidic glycosides in grape and can be applied as a new way for valorising grape pomace.

And the article was included in Journal of Chromatography A in 1997.COA of Formula: C10H22O3 The following contents are mentioned in the article:

Capillary gas chromatog.-mass spectrometric (CGC-MS) anal. was carried out on alkylpoly(ethylene glycol) ethers, derived from ethoxylation of C₄-C₁₀ alcs., both as synthetic mixtures and as residues in water after their biodegradation MS was used for the acquisition of spectra and for the recording of retention times and the areas of eluted components. Especially, alkylpoly(ethylene glycol) ethers were identified by a combination of electron impact (EI) mass spectra and by correlating their relative retention times with the structure of the mols. Using these correlations, the length of both the poly(ethylene glycol) part and the alkyl part of a mol. were determined Retention times of the eluted components were used for calculation of the relative retention characteristics. The peak areas were used to determine the concentration decreases of individual components as a function of the degradation time. Alkylpoly(ethylene glycol) ethers were analyzed in both the non-derivatized form and after their conversion to trimethylsilyl derivatives and acetates.

The Machilus genus (Lauraceae) had been extensively utilized in folk medicine due to its broad range of bioactivities. In the present study, a series of chromatog. separation of the methanol extract of stems of M. philippinensis led to the identification of thirty eight compounds totally. Among these, biscinnamophilin (1), machilupins A-C (2-4), machilutone A (5), and machilusoxide A (6) were new compounds reported for the first time. In addition, 5 was characterized with a unprecedented carbon skeleton. Other known compounds, including the major compounds cinnamophilin (7) and meso-dihydroguaiaretic acid (8), are identified by comparison of their phys. and spectroscopic data with reported values. One of the reported compounds, cinnamophilin A (10), should be revised as dehydroguaiaretic acid (9) after careful comparison of all the ¹H and ¹³ C NMR data. Moreover, the neuroprotective activity of cinnamophilin (7) was examined in a primary cortical neuron culture and the results indicated that 7 was effective against glutamate induced excitotoxicity.

Absorption, Distribution, Metabolism, and Excretion of the Main Olive Tree Phenols and Polyphenols: A Literature Review was written by Galmes, Sebastia;Reynes, Barbara;Palou, Mariona;Palou-March, Andreu;Palou, Andreu. And the article was included in Journal of Agricultural and Food Chemistry in 2021.Application of 2380-78-1 The following contents are mentioned in the article:

A review. The effects of olive tree (poly)phenols (OPs) are largely dependent upon their bioavailability and metabolization by humans. Absorption, distribution, metabolism, and excretion (ADME) are fundamental for the nutritional efficacy and toxicol. impact of foods containing OPs. This review includes studies on the administration of hydroxytyrosol (HT), oleuropein (Ole), or other OPs and foods, products, or mixtures that contain them. Briefly, data from in vivo studies indicate that OPs are absorbable by intestinal cells. Both absorption and bioavailability depend upon each compound and/or the matrix in which it is contained. OPs metabolism begins in enterocytes and can also continue in the liver. Metabolic phase I mainly consists of the hydrolysis of Ole, which results in an increase in the HT content. Phase II metabolic reactions involve the conjugation of (poly)phenols mainly with glucuronide and sulfate groups. This review offers a complete perspective of the ADME processes of OPs, which could support the future nutritional and/or toxicol. studies in this area. This study involved multiple reactions and reactants, such as 4-Hydroxy-3-methoxyphenethanol (cas: 2380-78-1Application of 2380-78-1).

4-Hydroxy-3-methoxyphenethanol (cas: 2380-78-1) belongs to ethers.

Controlled lignosulfonate depolymerization via solvothermal fragmentation coupled with catalytic hydrogenolysis/hydrogenation in a continuous flow reactor was written by Brandi, Francesco;Antonietti, Markus;Al-Naji, Majd. And the article was included in Green Chemistry in 2021.Application of 2380-78-1 The following contents are mentioned in the article:

Sodium lignosulfonate (LS) was valorized to low mol. weight (M_w) fractions by combining solvothermal (SF) and catalytic hydrogenolysis/hydrogenation fragmentation (SHF) in a continuous flow system. This was achieved in either alc./H₂O (EtOH/H₂O or MeOH/H₂O) or H₂O as a solvent and Ni on nitrogen-doped carbon as a catalyst. The tunability according to the temperature of both SF and catalytic SHF of LS has been sep. investigated at 150°C, 200°C, and 250°C. In SF, the minimal M_w was 2994 g mol^-1 at 250°C with a dispersity (D) of 5.3 using MeOH/H₂O. In catalytic SHF using MeOH/H₂O, extremely low M_w was found (433 mg gLS^-1) with a D of 1.2 combined with 34 mg gLS^-1. The monomer yield was improved to 42 mg gLS^-1 using dual catalytic beds. These results provide direct evidence that lignin is an unstable polymer at elevated temperatures and could be efficiently deconstructed under hydrothermal conditions with and without a catalyst. This study involved multiple reactions and reactants, such as 4-Hydroxy-3-methoxyphenethanol (cas: 2380-78-1Application of 2380-78-1).

4-Hydroxy-3-methoxyphenethanol (cas: 2380-78-1) belongs to ethers. Esters typically have a pleasant smell; those of low molecular weight are commonly used as fragrances and are found in essential oils and pheromones. 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.Application of 2380-78-1

Electroconductometric determination of completely engulfing Maxwell-type three-phase emulsions was written by Lee, Jong-Moon;Lim, Kyung-Hee. And the article was included in Journal of Industrial and Engineering Chemistry (Seoul, Republic of Korea) in 2003.Electric Literature of C10H22O3 The following contents are mentioned in the article:

The completely engulfing Maxwell-type morphol. of 3-phase emulsions was determined by the elec. method in which elec. conductivities of the emulsions were measured at various relative amounts of the equilibrium phases and fit to the conductivity equations of this morphol. The Maxwell-type 3-phase emulsions can be regarded as (i) the drops as 2-phase emulsions were dispersed in the continuous 3rd phase from the standpoint of the morphol. and (ii) the drops of one phase are dispersed in the continuous phase as emulsions composed of the other 2 phases from the standpoint of the way the 3-phase emulsions are prepared Previously the Maxwell-type morphol. could not be determined by the elec. method because the equation for the case (i) was used. However, the conductivities calculated by the equation for the case (ii) were in excellent agreement with the measured ones and the Maxwell-type morphol. could be determined This result implies that elec. conductivity behavior of completely engulfing Maxwell-type 3-phase emulsions should be examined from the way they are formed.

Prediction of flash points of pure organic compounds: Evaluation of the DIPPR database was written by Alibakhshi, A.;Mirshahvalad, H.;Alibakhshi, S.. And the article was included in Process Safety and Environmental Protection in 2017.Recommanded Product: 112-59-4 The following contents are mentioned in the article:

The flash point is one of the most important flammability properties of compounds for the design of inherently safe processes. Many models have been developed to predict the flash point using the DIPPR database. However, for only 740 of the 1628 organic compounds available in the DIPPR database, the data for both flash point and normal b.p. were exptl. determined For the other compounds, at least one of these properties was predicted and therefore is not appropriate for model development. The present study introduces a model to predict the flash points of pure organic compounds using their mol. structures and normal b.ps. The new model exploits the equality of the relative errors observed for the normal b.p. and flash point values predicted using the Joback method. Consequently, the relative error of the predicted normal b.ps. can be used as a scaling factor to modify the predicted flash points. The ability of the model to evaluate the accuracy of a database was investigated. The ratio of the relative error of the predicted flash point to the relative error of the predicted normal b.p. obtained using the Joback method was proposed as a measure to evaluate the accuracy of flash point data. 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. Carboxylic acid esters of low molecular weight are colourless, volatile liquids with pleasant odours, slightly soluble in water. 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.
