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 ...
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 ...

Hydrolysis of this Herz salt give the corresponding sodium thiolate, which can be further converted to the 2-aminothiophenol. [1] Herz-reaction. The 2-aminothiophenols are suitable for diazotization, giving benzothiadiazoles. [2] Instead the sodium 2-aminothiophenolate can be converted to a 1,3-benzothiazole. Herz-reaction application
[2] Benzo-1,2-3-dithiazolium salts can be prepared by the Herz reaction, which entails the reaction of an aniline with disulfur dichloride. Hydrolysis of this "Herz salt" gives the corresponding sodium thiolate, which can be further converted to the 2-aminothiophenol. [3] Herz-reaction. Appel's salt is an example of a 1,2,3-dithiazolium.

4-Aminophenol (or para-aminophenol or p-aminophenol) is an organic compound with the formula H 2 NC 6 H 4 OH. Typically available as a white powder, [3] it is commonly used as a developer for black-and-white film, marketed under the name Rodinal.
1,2,3-benzothiadiazole is much less nucleophilic than naphthalene. Nitration is slow. [8] For that reason, many of its simple derivatives have been made from 2-aminothiophenols already having additional substituents. [7] 1,2,3-benzothiadiazole is a very weak base and alkylation reactions give exclusively the 3-amino quaternary salt. [9]
