And the article contained the following:

Caoyuanwang Baijiu (CYW), a mild-flavor style Baijiu (MSB), is popular in northern China. However, there is a lack of studies reporting its aroma-active components. The aroma compounds of five CYW samples were analyzed using gas chromatog.-olfactory-mass spectrometry coupled with aroma extraction dilution anal. Fifty-five aroma-active compounds were identified in CYW, of which 27 had odor activity values ≥ 1. Reconstituted models successfully simulated the aroma profiles of CYW. The omission tests elucidated that β-damascenone, di-Me trisulfide, Et pentanoate, butanoic acid, Et acetate, 3-methylbutanal, Et lactate, hexanoic acid, γ-nonalactone, 3-hydroxy-2-butanone, Et butanoate, 1-propanol, 4-(ethoxymethyl)-2-methoxy-phenol, and vanillin were key odorants in CYW. The addition test confirmed the significant influence of di-Me trisulfide on Chen-aroma note. Nine key odorants were identified as the differential quality-markers, and 85.71% key odorants were predicted using the partial least square regression (PLSR) anal., indicating the applicability of PLSR in selecting the target compounds for omission tests. The experimental process involved the reaction of 1,2-Dimethoxybenzene(cas: 91-16-7).Application of 91-16-7

On July 16, 2021, Thorwart, Thaddaus; Roth, Daniel; Greb, Lutz published an article.Quality Control of 1,2-Dimethoxybenzene The title of the article was Bis(pertrifluoromethylcatecholato)silane: Extreme Lewis Acidity Broadens the Catalytic Portfolio of Silicon. And the article contained the following:

Given its earth abundance, Si is ideal for constructing Lewis acids of use in catalysis or materials science. Neutral silanes were limited to moderate Lewis acidity, until halogenated catecholato ligands provoked a significant boost. However, catalytic applications of bis(perhalocatecholato)silanes were suffering from very poor solubility and unknown deactivation pathways. The novel per(trifluoromethyl)catechol, H2catCF3, and adducts of its Si complex Si(catCF3)2 (1) are described. According to the computed F- ion affinity, 1 ranks among the strongest neutral Lewis acids currently accessible in the condensed phase. The improved robustness and affinity of 1 enable deoxygenations of aldehydes, ketones, amides, or phosphine oxides, and a carbonyl-olefin metathesis. All those transformations have never been catalyzed by a neutral silane. Attempts to obtain donor-free 1 attest to the extreme Lewis acidity by stabilizing adducts with even the weakest donors, such as benzophenone or hexaethyl disiloxane. The experimental process involved the reaction of 1,2-Dimethoxybenzene(cas: 91-16-7).Quality Control of 1,2-Dimethoxybenzene

On November 5, 2020, Zhang, Cheng; Li, Jiaohong; Wu, Xiaomao; Long, Youhua; An, Huaming; Pan, Xinglu; Li, Ming; Dong, Fengshou; Zheng, Yongquan published an article.Recommanded Product: 1,2-Dimethoxybenzene The title of the article was Rapid degradation of dimethomorph in polluted water and soil by Bacillus cereus WL08 immobilized on bamboo charcoal-sodium alginate. And the article contained the following:

The presence of hazardous dimethomorph residues in the environment poses a threat to birds, aquatic organisms, and mammals. The novel pure strain, Bacillus cereus WL08, responsible for detoxifying dimethomorph was isolated from dimethomorph-polluted soil. The WL08 immobilized system was developed using bamboo charcoal (BC) and sodium alginate (SA). Immobilization significantly improved the WL08 tolerance and stability. Under optimal conditions (pH 7.0 and 30°), free and immobilized WL08 degraded 66.95 and 96.88% of 50 mg/L dimethomorph within 72 h, resp. WL08 effectively degraded dimethomorph to simple products which had lower toxic than dimethomorph. In a continuous reactor, immobilized WL08 removed 85.61% of dimethomorph for 30 days at a 50-100 mg/L influent concentration For field soil sprayed with 4.20 kg a.i./ha 80% dimethomorph water dispersible granules with immobilized WL08, a lower half-life (1.93 days) was observed vs. free WL08 (4.28 days) and natural dissipation (23.82 days). Immobilized WL08 is considered a tool to remove dimethomorph from water/soil systems. Results provided a feasible, microbe-based strategy to bioremediate dimethomorph-polluted environments. The experimental process involved the reaction of 1,2-Dimethoxybenzene(cas: 91-16-7).Recommanded Product: 1,2-Dimethoxybenzene

On May 7, 2021, Kim, Hyun Tae; Kang, Eunsu; Kim, Minkyu; Joo, Jung Min published an article.SDS of cas: 91-16-7 The title of the article was Synthesis of Bidentate Nitrogen Ligands by Rh-Catalyzed C-H Annulation and Their Application to Pd-Catalyzed Aerobic C-H Alkenylation. And the article contained the following:

A new class of bidentate ligands was prepared by a modular approach involving Rh-catalyzed C-H annulation reactions. The resulting conformationally constrained ligands enabled the Pd-catalyzed C-H alkenylation at electron-rich and sterically less hindered positions of electron-rich arenes while promoting the facile oxidation of Pd(0) intermediates by oxygen. This newly introduced ligand class was complementary to the ligands developed for Pd-catalyzed oxidative reactions and may find broad application in transition-metal-catalyzed reactions. The experimental process involved the reaction of 1,2-Dimethoxybenzene(cas: 91-16-7).SDS of cas: 91-16-7

Brown, Ryan K.; Hooper, Thomas N.; Rekhroukh, Feriel; White, Andrew J. P.; Costa, Paulo J.; Crimmin, Mark R. published an article in 2021, the title of the article was Alumination of aryl methyl ethers: switching between sp2 and sp3 C-O bond functionalisation with Pd-catalysis.Name: 1,2-Dimethoxybenzene And the article contains the following content:

The reaction of aluminum(I) β-diketiminate [(ArN:CMeCHCMe:NAr)Al] (Ar = 2,6-iPr2C6H3) with aryl Me ethers proceeded with alumination of the sp3 C-O bond. The selectivity of this reaction could be switched by inclusion of a catalyst. In the presence of [Pd(PCy3)2], chemoselective sp2 C-O bond functionalization was observed Kinetic isotope experiments and DFT calculations support a catalytic pathway involving the ligand-assisted oxidative addition of the sp2 C-O bond to a Pd-Al intermetallic complex. The experimental process involved the reaction of 1,2-Dimethoxybenzene(cas: 91-16-7).Name: 1,2-Dimethoxybenzene

Applications to late-stage syntheses. And the article contained the following:

Rose Bengal-photocatalyzed perfluorohexylation of olefins, alkynes and electron-rich aromatic compounds in water was achieved employing perfluorohexyl iodide as fluoroalkyl source and TMEDA as sacrificial donor under green LED irradn to afford perfluoro compounds R1CHICH2C6F13 [R1 = CH2OPh, CHOH(CH2)5], R2HC=CHC6F13 [R2 = Ph, n-pentyl, (D)-(-)Norgestreyl] and I [R3 = 4-Me, 4-NO2, 2,6-(Me)2, etc.; R4 = OMe, NH2]. Alkenes and alkynes rendered products derived from the atom transfer radical addition (ATRA) pathway, and in the case of alkynes, exclusively as E-stereoisomers. These were the first examples of photocatalyzed ATRA reactions carried out excursively in water alone. The reactions of aromatic compounds under the current protocol in water present the advantage of employing a perfluoroalkyl iodide (C6F13-I) as source of perfluorohexyl radicals. Examples of photocatalytic late-stage incorporations of fluoroalkyl moieties into two com. drugs of widespread used were reported. The experimental process involved the reaction of 1,2-Dimethoxybenzene(cas: 91-16-7).COA of Formula: C8H10O2

Javier; Decker, Michael published an article.Recommanded Product: 91-16-7 The title of the article was Azobioisosteres of Curcumin with Pronounced Activity against Amyloid Aggregation, Intracellular Oxidative Stress and Neuroinflammation. And the article contained the following:

Many (poly-)phenolic natural products, for example, curcumin and taxifolin, had been studied for their activity against specific hallmarks of neurodegeneration, such as amyloid-β 42 (Aβ42) aggregation and neuroinflammation. Due to their drawbacks, arising from poor pharmacokinetics, rapid metabolism and even instability in aqueous medium, the biol. activity of azobenzene compounds carrying a pharmacophoric catechol group I [R = H, Cl, NO2, MeO, EtO, Oi-Pr; R1 = OH, MeO], which had been designed as bioisoteres of curcumin had been examined Mol. simulations revealed the ability of these compounds to form a hydrophobic cluster with Aβ42, which adopts different folds, affecting the propensity to populate fibril-like conformations. Furthermore, the curcumin bioisosteres exceeded the parent compound in activity against Aβ42 aggregation inhibition, glutamate-induced intracellular oxidative stress in HT22 cells and neuroinflammation in microglial BV-2 cells. The most active compound prevented apoptosis of HT22 cells at a concentration of 2.5μM (83% cell survival), whereas curcumin only showed very low protection at 10μM (21% cell survival). The experimental process involved the reaction of 1,2-Dimethoxybenzene(cas: 91-16-7).Recommanded Product: 91-16-7
