Beltra, Marta; Tomas, Hector; Lopez, Juan C.; Borras, Fernando; Ropero, Ana B. published an article in 2022, the title of the article was Nutritional Description of Foods with Low- and No-Calorie Sweeteners in Spain: The BADALI Project.HPLC of Formula: 585-88-6 And the article contains the following content:

The use of low- and no-calorie sweeteners (LNCS) in foods has increased in recent years in response to the neg. effects of free sugar on health. However, the health impact of LNCS is still unclear. Studies of the prevalence of LNCS in foods have been published previously, including in Spain. However, the use of health (HCs) and nutrition claims (NCs) to promote these foods and a full nutritional characterization are largely lacking. For this purpose, we used the BADALI database with 4218 foods present in the Spanish market. Our results show that 9.3% of foods have LNCS (including both intense and polyols). Sucralose and acesulfame K were the intense sweeteners most frequently used (52.4% and 48.2%, resp.), whereas maltitol was the preferred polyol (20.3%). Of all foods with LNCS, 30% also had added sugar. Many more foods with LNCS presented HCs and NCs than those without. Sugar was the nutrient most frequently claimed in NCs for LNCS-containing foods, whereas vitamins were for those without these sweeteners. NCs compliance with regulation was similar in both conditions (60.1% for foods without and 63.9% for foods with LNCS). As expected, foods with LNCS had less total sugar content and energy. Surprisingly, the nutrient profile of yogurts with LNCS changed completely: less total and saturated fat, whereas more proteins and sodium. Biscuits with LNCS contained more fiber. The results of our study reveal that the prevalence of LNCS is becoming high in some food types in Spain and that foods containing LNCS are more frequently promoted with HCs/NCs. In addition, it confirms the general reduction in energy and sugar content expected in foods with LNCS. Furthermore, it suggests a reformulation of products beyond sugar content. The experimental process involved the reaction of SweetPearlR P300 DC Maltitol(cas: 585-88-6).HPLC of Formula: 585-88-6

On April 1, 2022, Liu, Can; Li, Kang; Shang, Rui published an article.Computed Properties of 386704-04-7 The title of the article was Arenethiolate as a Dual Function Catalyst for Photocatalytic Defluoroalkylation and Hydrodefluorination of Trifluoromethyls. And the article contained the following:

An arene thiolate with an appropriate substituent was photoactivated under visible light to function as both a strongly reducing electron-donating redox catalyst and a HAT catalyst to enable catalytic C-F activation of trifluoromethyl substrates for selective hydrodefluorination and coupling with various alkenes in the presence of formate salts. These reactions demonstrated the promising utility of arenethiolates as dual function photocatalysts. The synthetic utility of this method was demonstrated by the broad scope of amenable trifluoromethyl substrates, including trifluoromethylated (hetero)arenes, trifluoroacetates, and trifluoroacetamides, which exhibited high levels of chemoselectivity. The reaction efficacy allowed site-selective late-stage functionalization of multitrifluoromethylated bioactive compounds and pharmaceuticals. The experimental process involved the reaction of (6-(Trifluoromethyl)pyridin-3-yl)methanol(cas: 386704-04-7).Computed Properties of 386704-04-7

On March 29, 2021, Zhao, Xiao-Jing; Li, Zi-Hao; Ding, Tong-Mei; Tian, Jin-Miao; Tu, Yong-Qiang; Wang, Ai-Fang; Xie, Yu-Yang published an article.Recommanded Product: (R)-2-Amino-2-(m-tolyl)ethanol The title of the article was Enantioselective Synthesis of 3,3′-Disubstituted 2-Amino-2′-hydroxy-1,1′-binaphthyls by Copper-Catalyzed Aerobic Oxidative Cross-Coupling. And the article contained the following:

A challenging direct asym. catalytic aerobic oxidative cross-coupling of 2-naphthylamine and 2-naphthol, using a novel CuI/SPDO system, has been successfully developed for the first time. Enantioenriched 3,3′-disubstituted NOBINs were achieved and could be readily derived to divergent chiral ligands and catalysts. This reaction features high enantioselectivities (up to 96% ee) and good yields (up to 80%). The DFT calculations suggest that the F-H interactions between CF3 of L17 and H-1,8 of 2-naphthol, and the π-π stacking between the two coupling partners could play vital roles in the enantiocontrol of this cross-coupling reaction. The experimental process involved the reaction of (R)-2-Amino-2-(m-tolyl)ethanol(cas: 926292-63-9).Recommanded Product: (R)-2-Amino-2-(m-tolyl)ethanol

On April 30, 2000, Femia, Frank J.; Babich, John W.; Zubieta, Jon published an article.Reference of 2,2′-(tert-Butylazanediyl)diethanol The title of the article was Structural systematics of the {ReO}3+ core with ‘3+2’ ligand donor sets. And the article contained the following:

The reactions of [ReOCl3(PPh3)2] with the appropriate tridentate and bidentate ligands provide a facile route for the synthesis of a diverse family of compounds of the {Re(V)O}3+ core with a ‘3+2′ ligand set. The structural prototype for the series is [ReO{OCH2CH2SCH2CH2O}{OCH2CH2SCH2CH2OH}] (1) which exhibits distorted octahedral geometry, defined by the two oxygen and sulfur donors of the tridentate ligand in a facial arrangement, the oxygen and sulfur donors of the bidentate ligand, and the oxo-donor. Compounds 2-5 are variants [ReO(OCH2CH2SCH2CH2O)(S and N)] where S and N is a bidentate ligand of the mercaptopyridine or mercaptopyrimidine class. Similarly, compounds 6-17 are [ReO(OCH2CH2NRCH2CH2O)(S and N)] with the same bidentate ligands as for 2-5 and R = Me, Et, Bu, and t-Bu. The experimental process involved the reaction of 2,2’-(tert-Butylazanediyl)diethanol(cas: 2160-93-2).Reference of 2,2′-(tert-Butylazanediyl)diethanol

On August 4, 2020, Wu, Yan; Venier, Marta; Hites, Ronald A. published an article.Formula: C14H22O The title of the article was Broad Exposure of the North American Environment to Phenolic and Amino Antioxidants and to Ultraviolet Filters. And the article contained the following:

This work comprehensively assessed three suites of commonly used synthetic additives: phenolic and amino antioxidants and UV filters. Concentrations of 47 such compounds and their transformation products were measured in 20 atm. particle samples collected at Chicago, Illinois, in 21 Canadian e-waste dust samples, in 32 Canadian and US residential dust samples, and in 10 Chicago Sanitary and Ship Canal sediment samples. Despite their large US production volumes, environmental data on antioxidants and UV filters in North America is limited. These compounds were detected in all samples, indicating their ubiquitous distribution in the North American environment. The most prevalent compounds were 2,6-di-t-butyl-p-benzoquinone, diphenylamine, 4,4′-di-t-octyl diphenylamine, 2,4-dihydroxybenzophenone, and 2-hydroxy-4-methoxybenzophenone. E-waste dust contained significantly greater total concentrations of these compounds than Canadian residential dust; intermediate levels were detected in US residential dust. Sediment had relatively high N,N’-diphenylbenzidine concentrations whose source was unclear, and some benzotriazole UV filters. Daily intake rates via dust ingestion for these compounds were 1-10 ng/kg-day for adults to 10-100 ng/kg-day for toddlers. Due to the wide distribution of these compounds in ambient and built environments, future research on their potential toxic effects on people and ecosystems is important. The experimental process involved the reaction of 2,4-Di-tert-butylphenol(cas: 96-76-4).Formula: C14H22O
