Template:Chembox Footer/trackingTemplate:Short description
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)[4] or from resorcinol via a substitution reaction with ammonium hydroxide.[5]
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]
