• Aminophenol — A bifunctional organic compound with amphoteric character, derived from phenol by replacing a hydrogen atom on the aromatic ring with an amino group (-NH2). It has three positional isomers (ortho, meta, and para), of which para-aminophenol is the most industrially important, serving as a key structural intermediate in the synthesis of paracetamol, hair dyes, and photographic developers.
