m-Aminophenol, identifiable by CAS 591‑27‑5, functions as a versatile aromatic amine intermediate used primarily in the synthesis of functional dyes and specialty chemicals. Chemically defined as 3-Aminophenol, this crystalline powder serves as a critical coupling agent in oxidative hair colorants and a precursor for fluorescent dyes like Rhodamine B. The substance, often referred to as 3-Hydroxyaniline or m-Hydroxyaniline in synthesis pathways, acts as a key building block for producing agrochemicals and pharmaceutical compounds involving benzoxazole structures. We facilitate bulk supply of this fine chemical with competitive factory pricing, capable of meeting customized specifications for purity and color stability, backed by comprehensive MSDS, TDS, COA documentation.

FAQ - Technical & Supply Chain
-
Q:
Is m‑aminophenol different from o‑aminophenol or p‑aminophenol?
A: Yes. These are positional isomers with different substitution patterns on the benzene ring and are treated as distinct substances with separate CAS numbers. -
Q:
What is the primary industrial function of this intermediate in dye manufacturing?
A: m-Aminophenol is typically applied as a coupling component in the production of azo dyes and optical brighteners, reacting with diazonium salts to form stable color compounds.
