And the article was included in RSC Advances in 2020.Computed Properties of C8H18O4 This article mentions the following:

Solvate ionic liquids (SILs), comprising long-lived, Li solvate cations and counter anions, serve as highly Li-ion-conductive and non-flammable electrolytes for use in lithium secondary batteries. In this work, we synthesized a series of novel redox-active glyme(oligoether)-Li salt-based SILs, consisting of a sym. ([Li(G3)]⁺) or asym. ([Li(G3Bu)]⁺) triglyme-Li salt complex and redox-active tetrahalogenoferrate ([FeX]^– (X = Br₄, Cl₃Br, Cl₄)), for use as the catholyte in semi-liquid lithium secondary batteries. The successful formation of stable molten complexes of [Li(G3/G3Bu)][FeX] was confirmed by Raman spectroscopy and thermogravimetry. The m.p. (T_m) depended on both the mol. weights of the complex anions and the structures of the complex cations. [Li(G3)][FeCl₄] comprised complex cations with a sym. structure, and the smallest complex anions showed the lowest T_m of 28.2°C. The redox properties of the [FeX]^–/[FeX]^2- couple strongly suggested the suitability of [Li(G3/G3Bu)][FeX] as a catholyte. The discharge capacities of semi-liquid lithium secondary batteries utilizing the [Li(G3/G3Bu)][FeX] catholyte depended on the structure of the SILs, and the cell with [Li(G3)][FeCl₄] showed the highest capacity with relatively good capacity retention. This study confirmed the feasibility of the glyme-based redox-active SILs as catholytes for scalable redox-flow type batteries. In the experiment, the researchers used many compounds, for example, 2,5,8,11-Tetraoxadodecane (cas: 112-49-2Computed Properties of C8H18O4).

2,5,8,11-Tetraoxadodecane (cas: 112-49-2) belongs to ethers. Ether is less polar than esters, alcohols or amines because of the oxygen atom that is unable to participate in hydrogen bonding due to the presence of bulky alkyl groups on both sides of the oxygen atom. But ether is more polar than alkenes. Ethyl ether is an excellent solvent for extractions and for a wide variety of chemical reactions. It is also used as a volatile starting fluid for diesel engines and gasoline engines in cold weather. Dimethyl ether is used as a spray propellant and refrigerant. Methyl t-butyl ether (MTBE) is a gasoline additive that boosts the octane number and reduces the amount of nitrogen-oxide pollutants in the exhaust. The ethers of ethylene glycol are used as solvents and plasticizers.Computed Properties of C8H18O4

A free radical alkylation of quinones with olefins was written by Liu, Shuai;Shen, Tong;Luo, Zaigang;Liu, Zhong-Quan. And the article was included in Chemical Communications (Cambridge, United Kingdom) in 2019.Electric Literature of C9H10O4 This article mentions the following:

We demonstrated herein an Fe(III)-mediated radical alkylation of quinones. A wide range of bioactive mols. with quinone motifs could be rapidly synthesized by using readily available and inexpensive NaBH₄/NaBD₄ with alkenes at room temperature under open flask conditions. In the experiment, the researchers used many compounds, for example, 2,3-Dimethoxy-5-methylcyclohexa-2,5-diene-1,4-dione (cas: 605-94-7Electric Literature of C9H10O4).

2,3-Dimethoxy-5-methylcyclohexa-2,5-diene-1,4-dione (cas: 605-94-7) belongs to ethers. Ethers are good solvents partly because they are not very reactive. Most ethers can be cleaved, however, by hydrobromic acid (HBr) to give alkyl bromides or by hydroiodic acid (HI) to give alkyl iodides. Ethers can form hydrogen bonds with other molecules (alcohols, amines, etc.) that have O―H or N―H bonds. The ability to form hydrogen bonds with other compounds makes ethers particularly good solvents for a wide variety of organic compounds and a surprisingly large number of inorganic compounds.Electric Literature of C9H10O4

Copper-Catalyzed Direct C-H Trifluoromethylation of Quinones was written by Wang, Xi;Ye, Yuxuan;Ji, Guojing;Xu, Yan;Zhang, Songnan;Feng, Jiajie;Zhang, Yan;Wang, Jianbo. And the article was included in Organic Letters in 2013.Formula: C9H10O4 This article mentions the following:

An efficient and practical methodol. has been developed to introduce the CF₃ group onto quinones through Cu(I)-catalyzed direct C-H trifluoromethylation of quinones. E.g., in presence of CuI in t-BuOH/DCM, direct C-H trifluoromethylation of quinone derivative (I, R = H) by electrophilic trifluoromethylation reagent (II) gave 77% trifluoromethylated product (I, R = CF₃). In the experiment, the researchers used many compounds, for example, 2,3-Dimethoxy-5-methylcyclohexa-2,5-diene-1,4-dione (cas: 605-94-7Formula: C9H10O4).

2,3-Dimethoxy-5-methylcyclohexa-2,5-diene-1,4-dione (cas: 605-94-7) belongs to ethers. Ether is less polar than esters, alcohols or amines because of the oxygen atom that is unable to participate in hydrogen bonding due to the presence of bulky alkyl groups on both sides of the oxygen atom. Electron-deficient reagents are also stabilized by ethers. For example, borane (BH3) is a useful reagent for making alcohols. Pure borane exists as its dimer, diborane (B2H6), a toxic gas that is inconvenient and hazardous to use. Borane forms stable complexes with ethers, however, and it is often supplied and used as its liquid complex with tetrahydrofuran (THF).Formula: C9H10O4

Palladium-catalyzed aryl amination- heck cyclization cascade: a one-flask approach to 3-substituted indoles was written by Jensen, Thomas;Pedersen, Henrik;Bang-Andersen, Benny;Madsen, Robert;Joergensen, Morten. And the article was included in Angewandte Chemie, International Edition in 2008.HPLC of Formula: 56619-93-3 This article mentions the following:

A Pd/dppf-based catalyst provides access to the title compounds from 1,2-dihalogenated aromatic compounds and allylic amines in a single reaction flask. The initial aryl amination step occurs with excellent selectivity for the aryl iodide to ensure the formation of a single indole regioisomer, which can be functionalized in situ by N-arylation. In the experiment, the researchers used many compounds, for example, N-(3-Methoxyphenyl)pivalamide (cas: 56619-93-3HPLC of Formula: 56619-93-3).

N-(3-Methoxyphenyl)pivalamide (cas: 56619-93-3) belongs to ethers. Ethers are good solvents partly because they are not very reactive. Most ethers can be cleaved, however, by hydrobromic acid (HBr) to give alkyl bromides or by hydroiodic acid (HI) to give alkyl iodides. Ethers feature bent C–O–C linkages. In dimethyl ether, the bond angle is 111° and C–O distances are 141 pm. The barrier to rotation about the C–O bonds is low. The bonding of oxygen in ethers, alcohols, and water is similar. In the language of valence bond theory, the hybridization at oxygen is sp3.HPLC of Formula: 56619-93-3

An O-Benzyl Phosphonamidate Prodrug of Tenofovir for the Treatment of Hepatitis B Virus Infection was written by Zhang, Qianqian;Peng, Youmei;Hou, Jiao;Chen, Yanhong;Liu, Bingjie;Zhang, Pinghu;Yu, Wenquan;Chang, Junbiao. And the article was included in Journal of Medicinal Chemistry in 2022.Quality Control of (4-Methoxyphenyl)methanol This article mentions the following:

A series of new O-(substituted benzyl) phosphoramidate prodrugs of tenofovir for the treatment of hepatitis B virus (HBV) infections have been designed and synthesized. An investigation of structure-activity relationships revealed that the compound bearing an o-methylbenzyl group (1a) has the most potent in vitro anti-HBV activity. This prodrug (1a) was well-tolerated in KM mice via intragastric administration at a dosage of up to 1.5 g/kg. In DHBV-infected ducks, prodrug 1a displayed a good inhibitory effect on the viral DNA replication in both the serum and the liver in a time- and dose-dependent manner and did not cause any necrosis, hemorrhage, or inflammatory response in the animal livers. Further investigation demonstrated that prodrug 1a achieved a higher exposure of the bioactive metabolite (tenofovir diphosphate, TFV-DP) in the liver, the target organ for the treatment of HBV infection, than tenofovir alafenamide fumarate (TAF) did at an equimolar dose. In the experiment, the researchers used many compounds, for example, (4-Methoxyphenyl)methanol (cas: 105-13-5Quality Control of (4-Methoxyphenyl)methanol).

(4-Methoxyphenyl)methanol (cas: 105-13-5) belongs to ethers. Of all the functional groups, ethers are the least reactive ones. Ether bonds are quite stable towards bases, oxidizing agents and reducing agents. At room temperature, ethers are pleasant-smelling colourless liquids. Relative to alcohols, ethers are generally less dense, are less soluble in water, and have lower boiling points. They are relatively unreactive, and as a result they are useful as solvents for fats, oils, waxes, perfumes, resins, dyes, gums, and hydrocarbons. Vapours of certain ethers are used as insecticides, miticides, and fumigants for soil.Quality Control of (4-Methoxyphenyl)methanol

1-Methoxy-4-((4-propylphenyl)ethynyl)benzene (cas: 39969-26-1) belongs to ethers. Ether is less polar than esters, alcohols or amines because of the oxygen atom that is unable to participate in hydrogen bonding due to the presence of bulky alkyl groups on both sides of the oxygen atom. But ether is more polar than alkenes. The unique properties of ethers (i.e., that they are strongly polar, with nonbonding electron pairs but no hydroxyl group) enhance the formation and use of many reagents. For example, Grignard reagents cannot form unless an ether is present to share its lone pair of electrons with the magnesium atom. Complexation of the magnesium atom stabilizes the Grignard reagent and helps to keep it in solution.Quality Control of 1-Methoxy-4-((4-propylphenyl)ethynyl)benzene

Multiple Hydrogen Bond Channel Structural Electrolyte for an Enhanced Carbon Fiber Composite Battery was written by Choi, Jaehoon;Zabihi, Omid;Varley, Russell;Zhang, Jane;Fox, Bronwyn L.;Naebe, Minoo. And the article was included in ACS Applied Energy Materials in 2022.COA of Formula: C8H18O4 This article mentions the following:

Structural batteries made of carbon fiber composites have been receiving great attention for automotive application in the last decade. However, a structural battery electrolyte (SBE) for the structural batteries is conventionally dependent on utilizing highly volatile carbonate-derivative liquid electrolytes to provide moderate ionic conduction. This study introduces a SBE which fabricates as a two-phase system via reaction-induced phase transition as well as includes a hybridized electrolyte, consisting of a low flammability electrolyte with a solid additive-inducing multihydrogen bond. The proposed SBE is composed of a vinyl ester polymer containing triethylene glycol di-Me ether (TriG) and cyclohexanedimethanol (CHDM) as a quasi-solid additive. Confirmed by Fourier transform IR, Raman, and ⁷Li-NMR results, the contents of CHDM in the SBE structure play a crucial role not only through the plasticizing effect but also through the formation of a multidimension channel via a hydrogen bond, thereby contributing to enhancing the motion of the cation in the SBE. The optimized SBE (Li-TriG-CHDM10) shows an ionic conductivity of 2.0 x 10^-4 S cm^-1 with an E’ of ~300 MPa at ambient temperature To exhibit the possibility for a structural battery, the carbon fiber composite lamina was fabricated using an optimized SBE and evaluated as a battery half-cell, showing the potential of a high bearing mech. load and ion transport between the carbon fibers and the electrolytes. In the experiment, the researchers used many compounds, for example, 2,5,8,11-Tetraoxadodecane (cas: 112-49-2COA of Formula: C8H18O4).

Highly dispersed palladium nanoparticles supported on an imidazolium-based ionic liquid polymer: an efficient catalyst for oxidation of alcohols was written by Karimi, Z.;Hassanpour, A.;Kangari, S.;Marjani, A.. And the article was included in Russian Chemical Bulletin in 2022.Recommanded Product: 105-13-5 This article mentions the following:

An efficient and stable nanocatalyst for selective oxidation of alcs. was developed. It contains palladium nanoparticles, which are well distributed throughout the network of a copolymer based on an ionic liquid The synthesized nanomaterials were characterized by various techniques such as nitrogen adsorption-desorption anal., thermal gravimetric anal., TEM, and FTIR spectroscopy. A high surface area and the appropriate pore size of the nanocatalyst make active metal sites accessible to reagents, whereas the presence of an ionic liquid in the network of the polymer structure creates a good environment for the leaching protection and stabilization of extremely dispersed palladium nanoparticles. The availability and abundance of active sites of highly dispersed palladium nanoparticles make the synthesized nanocatalyst very promising for oxidation of alcs. The nanocatalyst has a number of features such as a high surface area, an appropriate size of pores with high catalytic activity, high thermal stability of the nanostructures, and low amounts of the ionic liquid needed for its synthesis. Using this nanocatalyst, carbonyl compounds were prepared from the corresponding alcs. in high yields. Addnl., the prepared nanocatalyst can easily be recovered by centrifugation after completion of the reactions and was reused five times without a significant loss in its catalytic activity. In the experiment, the researchers used many compounds, for example, (4-Methoxyphenyl)methanol (cas: 105-13-5Recommanded Product: 105-13-5).

(4-Methoxyphenyl)methanol (cas: 105-13-5) belongs to ethers. The oxygen atom in ethers are more electronegative than carbon, thus the hydrogens which are alpha to the ethers are more acidic than the simple hydrocarbons. The unique properties of ethers (i.e., that they are strongly polar, with nonbonding electron pairs but no hydroxyl group) enhance the formation and use of many reagents. For example, Grignard reagents cannot form unless an ether is present to share its lone pair of electrons with the magnesium atom.

Influence of Porosity of Sulfide-Based Artificial Solid Electrolyte Interphases on Their Performance with Liquid and Solid Electrolytes in Li and Na Metal Batteries was written by Lim, Kyungmi;Fenk, Bernhard;Kuester, Kathrin;Acartuerk, Tolga;Weiss, Juergen;Starke, Ulrich;Popovic, Jelena;Maier, Joachim. And the article was included in ACS Applied Materials & Interfaces in 2022.SDS of cas: 112-49-2 This article mentions the following:

Realization of all-solid-state batteries combined with metallic Li/Na is still hindered due to the unstable interface between the alkali metal and solid electrolytes, especially for highly promising thiophosphate materials. Artificial and uniform solid-electrolyte interphases (SEIs), serving as thin ion-conducting films, have been considered as a strategy to overcome the issues of such reactive interfaces. Here, we synthesized sulfide-based artificial SEIs (Li_xS_y and Na_xS_y) on Li and Na by solid/gas reaction between the alkali metal and S vapor. The synthesized films are carefully characterized with various chem./electrochem. techniques. We show that these artificial SEIs are not beneficial from an application point of view since they either contribute to addnl. resistances (Li) or do not prevent reactions at the alkali metal/electrolyte interface (Na). We show that Na_xS_y is more porous than Li_xS_y, supported by (i) its rough morphol. observed by focused ion beam-SEM, (ii) the rapid decrease of R_interface (interfacial resistance) in Na_xS_y-covered-Na sym. cells with liquid electrolyte upon aging under open-circuit potential, and (iii) the increase of R_interface in Na_xS_y-covered-Na solid-state sym. cells with Na₃PS₄ electrolyte. The porous SEI allows the penetration of liquid electrolyte or alkali metal creep through its pores, resulting in a continuous chem. reaction. Hence, porosity of SEIs in general should be carefully taken into account in the application of batteries containing both liquid electrolyte and solid electrolyte. In the experiment, the researchers used many compounds, for example, 2,5,8,11-Tetraoxadodecane (cas: 112-49-2SDS of cas: 112-49-2).

Identification and characterization of five new classes of chlorogenic acids in burdock (Arctium lappa L.) roots by liquid chromatography/tandem mass spectrometry was written by Jaiswal, Rakesh;Kuhnert, Nikolai. And the article was included in Food & Function in 2011.HPLC of Formula: 6972-61-8 This article mentions the following:

Burdock (Arcticum lappa L.) roots are used in folk medicine and also as a vegetable in Asian countries especially Japan, Korea, and Thailand. We have used LC-MSⁿ (n = 2-4) to detect and characterize in burdock roots 15 quant. minor fumaric, succinic, and malic acid-containing chlorogenic acids, 11 of them not previously reported in nature. These comprise 3-succinoyl-4,5-dicaffeoyl or 1-succinoyl-3,4-dicaffeoylquinic acid, 1,5-dicaffeoyl-3-succinoylquinic acid, 1,5-dicaffeoyl-4-succinoylquinic acid, and 3,4-dicaffeoyl-5-succinoylquinic acid (M_r 616); 1,3-dicaffeoyl-5-fumaroylquinic acid and 1,5-dicaffeoyl-4-fumaroylquinic acid (M_r 614); 1,5-dicaffeoyl-3-maloylquinic acid, 1,4-dicaffeoyl-3-maloylquinic acid, and 1,5-dicaffeoyl-4-maloylquinic acid (M_r 632); 1,3,5-tricaffeoyl-4-succinoylquinic acid (M_r 778); 1,5-dicaffeoyl-3,4-disuccinoylquinic acid (M_r 716); 1,5-dicaffeoyl-3-fumaroyl-4-succinoylquinic acid and 1-fumaroyl-3,5-dicaffeoyl-4-succinoylquinic acid (M_r 714); dicaffeoyl-dimaloylquinic acid (M_r 748); and 1,5-dicaffeoyl-3-succinoyl-4-dimaloylquinic acid (M_r 732). All the structures have been assigned on the basis of LC-MSⁿ patterns of fragmentation, relative hydrophobicity, and analogy of fragmentation patterns if compared to caffeoylquinic acids. In the experiment, the researchers used many compounds, for example, 3-(2,4-Dimethoxyphenyl)acrylic acid (cas: 6972-61-8HPLC of Formula: 6972-61-8).

3-(2,4-Dimethoxyphenyl)acrylic acid (cas: 6972-61-8) belongs to ethers. Relative to alcohols, ethers are generally less dense, are less soluble in water, and have lower boiling points. They are relatively unreactive, and as a result they are useful as solvents for fats, oils, waxes, perfumes, resins, dyes, gums, and hydrocarbons. Vapours of certain ethers are used as insecticides, miticides, and fumigants for soil. Autoxidation is the spontaneous oxidation of a compound in air. In the presence of oxygen, ethers slowly autoxidize to form hydroperoxides and dialkyl peroxides. If concentrated or heated, these peroxides may explode. To prevent such explosions, ethers should be obtained in small quantities, kept in tightly sealed containers, and used promptly.HPLC of Formula: 6972-61-8
