2-Aminophenol is an organic compound with the formula C₆H₄(OH)NH₂. Along with its isomer 4-aminophenol, it is an amphoteric molecule and a reducing agent. It is a useful reagent for the synthesis of dyes and heterocyclic compounds. Reflecting its slight hydrophilic character, white powder is moderately soluble in alcohols and can be recrystallised from hot water. O-Aminophenol should avoid the condition like incompatible materials,light. It is incompatibilities with  other materials light, acids, acid chlorides, acid anhydrides, chloroformates. Its hazardous decomposition products are nitrogen oxides, carbon monoxide, carbon dioxide. Its hazardous polymerization has not been reported.

Uses of 2-Aminophenol: 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. 2-Aminophenol is an intermediate in the synthesis of dyes. It is particularly useful in yielding tridentate ligands for metal-complex dyes when diazotized and coupled to a phenol, naphthol, or other aromatic or resonant dye species. Metal complex dyes using copper or chromium are commonly used for producing dull colors. Tridentate ligand dyes are particularly useful, since they are more stable than their bi- or mono-dentate counterparts.
