2-Aminophenol is an organic compound with the formula C 6 H 7 NO. Along with its isomer 4-aminophenol , it is an amphoteric molecule and a reducing agent . It is a useful reagent for the synthesis of dyes and heterocyclic compounds . [ 3 ]
2-Aminothiophenol is a precursor to benzothiazoles, some of which are bioactive or are commercial dyes. Isomers of aminothiophenols include 3-aminothiophenol and 4-aminothiophenol. 2-Aminothiophenol can prepared in two steps, starting with the reaction of aniline with carbon disulfide followed by hydrolysis of the resulting ...
The three component synthesis of the direct etonitazene precursor, 2-(4-Ethoxybenzyl)-5-nitro-1H-benzoimidazole, consists of a 2-Bromo- or 2-Iodo-5-nitro-phenylamine (1.0 molar equivalent), a 4-substituted benzaldehyde (1.2 equiv), and sodium azide (2 equiv). The 2-Halo-5-nitro-phenylamine requires a bromo or iodo group for optimal activity. 2 ...
Benzimidazole is a base: C 6 H 4 N(NH)CH + H + → [C 6 H 4 (NH) 2 CH] + It can also be deprotonated with stronger bases: C 6 H 4 N(NH)CH + LiH → Li [C 6 H 4 N 2 CH] + H 2. The imine can be alkylated and also serves as a ligand in coordination chemistry. The most prominent benzimidazole complex features N-ribosyl-dimethylbenzimidazole, as ...
5,6-Dimethylbenzimidazole is a natural benzimidazole derivative. It is a component of vitamin B 12 where it serves as a ligand for the cobalt atom. [1] 5,6-Dimethylbenzimidazole is biosynthesized from flavin mononucleotide by the enzyme 5,6-dimethylbenzimidazole synthase. [2]
Bemethyl has been shown to preserve both physical and mental capacity in high-altitude, low-oxygen environments, particularly by its effect in helping control excess serum levels of cholesterol and bilirubin, which are known to have negative effects especially during adjustment to high-altitude environments.
The structure-activity relationship of the drug class has been explored to a reasonable extent. The optimal substitution pattern is fairly tightly defined (i.e. N,N-diethyl on the amine nitrogen, 4-ethoxy on the benzyl ring and 5-nitro on the benzimidazole ring), but even derivatives incorporating only some of these features are still potent opioids.
