3-Aminophenol can 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.
One of the most relevant applications of the substance is the synthesis of 3-(diethylamino)phenol, key intermediate 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.
