2-Aminothiophenol is an organosulfur compound with the formula C 6 H 4 (SH)(NH 2). It is a colorless oily solid, although impure samples can be deeply colored. It is soluble in organic solvents and in basic water. 2-Aminothiophenol is a precursor to benzothiazoles, some of which are bioactive or are commercial dyes.
2-Aminophenol has a variety of uses. As a reducing agent, it is marketed under the names of Atomal and Ortol to develop black-and-white photographs. [3] 2-Aminophenol is an intermediate in the synthesis of dyes. It is particularly useful in yielding metal-complex dyes when diazotized and coupled to a phenol, naphthol, or other aromatic or ...
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.
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 ...

It is the mercaptan of benzimidazole. It is a white solid that has been investigated as a corrosion inhibitor . The name is a misnomer because the compound is a thiourea , characterized with a short C=S bond length of 169 pm. [ 1 ] A similar situation applies to 2-mercaptoimidazole, which is also a thiourea properly called 2-imidazolidinethione ...

2-Aminobiphenyl (2-ABP) is an organic compound with the formula C 6 H 5 C 6 H 4 NH 2. It is an amine derivative of biphenyl. It is a colorless solid, although aged samples can appear colored even black. [1] Palladacycles obtained from 2-aminobiphenyl are popular catalysts for cross-coupling. [2] It is prepared by hydrogenation of 2 ...
