2-Aminothiophenol is an organosulfur compound with the formula C6H4(SH)(NH2). It is a colorless oily solid, although impure samples can be deeply colored. It is soluble in organic solvents and in basic water. It is a precursor to benzothiazoles, some of which are bioactive or are 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 mercaptobenzothiazole. It can also obtained by zinc reduction of 2-nitrobenzenesulfonyl chloride.
