What is 3-Aminophenol?
3-Aminophenol (CAS 591-27-5), also known as m-aminophenol, is an aromatic amine intermediate.
Where is 3-Aminophenol used?
- Dye synthesis: coupling component and reactive building block for azo dyes, developers and polymer curing agents
- Textile and leather dyeing: key intermediate for azo and mordant dyes that bond directly to fiber substrates
- Personal care: oxidative hair dye coupler that reacts with primary developers to produce tones
- Polymer and resin systems: curing agent and cross-linker for epoxy and urethane network formation
- Pharmaceutical and agrochemical producers rely on it as a synthetic intermediate.
Commercial specifications
- Technical and synthesis-grade material, purity typically 98% to 99%+ by HPLC
- Packaging in kilogram quantities through to bulk drum and bag formats
