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-Aminothiophenol can prepared in two steps, starting with the reaction of aniline with carbon disulfide followed by hydrolysis of the resulting mercaptobenzothiazole.
