3-Aminophenol is an organic compound with formula C6H4(NH2)(OH). It is an aromatic amine and a phenol. It is the meta isomer of 2-aminophenol and 4-aminophenol.
Preparation 3-Aminophenol is prepared by reduction of 3-nitrophenol. It can also be prepared by caustic fusion of 3-aminobenzenesulfonic acid (i.e. heating with NaOH to 245 °C for 6 hours) or from resorcinol via a substitution reaction with ammonium hydroxide.
Uses One of the most relevant applications of the substance is the synthesis of 3-(diethylamino)phenol, which is used for the preparation of several fluorescent dyes (e.g., rhodamine B). Other uses for the compound include hair dye colorants and stabilizers for chlorine-containing thermoplastics.
4-Aminosalicylic acid (PAS) is made by the Kolbe–Schmitt reaction of 3-aminophenol.
Some pesticides made from 3-aminophenol include the following: Formetanate, Mepronil, Karbutilate, Phenmedipham, Desmedipham & Phenisopham.
