3-Aminophenol
3-Aminophenol (CAS: 591-27-5) is an aromatic compound carrying both amino and hydroxyl groups, supplied as a white to off-white crystalline powder. The dual functionality makes it a valuable coupling component and intermediate for oxidative hair dyes, azo dyes, and pigments, and a building block for pharmaceutical and agrochemical actives. The electron-rich ring supports further acylation, alkylation, and diazotization chemistry. The material dissolves in common polar solvents and stores well when protected from air and light. Customers select it where a bifunctional aromatic intermediate with reliable coupling performance is required.
• Hair dyes: a standard coupling component in oxidative hair colorant systems.
• Dyes and pigments: an intermediate for azo dyes and organic pigments used in textiles and inks.
• Pharma and agrochemicals: a building block for active ingredient synthesis.
• Chemistry: amino and hydroxyl groups support acylation, alkylation, and diazotization.
