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 ...

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
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.
The traditional route is the reaction of 2-aminothiophenol and carbon disulfide: C 6 H 4 (NH 2)SH + CS 2 → C 6 H 4 (NH)SC=S + H 2 S. This method was developed by the discoverer of the compound, A. W. Hoffmann. Other routes developed by Hoffmann include the reactions of carbon disulfide with 2-aminophenol and of sodium hydrosulfide with ...
Goldberg reaction completed the formation of the phenothiazine ring and gave N,N-dimethyl-10H-phenothiazine-2-sulfonamide [1090-78-4] (6). Attachment of the sidechain by sodamide reaction with 1-(3-Chloropropyl)-4-Methylpiperazine [104-16-5] ( 7 ) completes the synthesis of Thioproperazine ( 8 ), respectively.
