Description

3-Aminophenol (CAS 591-27-5 ), commonly referred to as m-aminophenol, is an aromatic amine intermediate used across dye synthesis, hair color formulations, and specialty chemical manufacturing. It functions primarily as a coupling component and reactive building block in the production of azo dyes, developers, and polymer curing agents. In textile and leather dyeing, it serves as a key intermediate. It is used in synthesizing azo and mordant dyes that bond directly to fiber substrates. Personal care manufacturers use it as an oxidative hair dye coupler, where it reacts with primary developers to produce tones. In polymer and resin systems, it acts as a curing agent and cross-linker, contributing to epoxy and urethane network formation. Pharmaceutical and agrochemical producers also rely on it as a synthetic intermediate. It is essential for active ingredient manufacturing across various industrial sectors. 3-Aminophenol is supplied as an off-white to light brown crystalline powder for easy handling and processing. Technical and synthesis-grade material is the standard commercial offering, with purity levels typically ranging from 98% to 99%+ by HPLC. This ensures consistent performance in sensitive chemical reactions. Packaging is available in kilogram quantities through to bulk drum and bag formats to suit laboratory, pilot, and industrial-scale procurement.
