| Hazard Information | Back Directory | [Uses]
2-Amino-5-nitrophenol is used as an intermediate in the manufacture of several azo dyes, including CI Solvent Red 8, which is used for colouring synthetic resins, lacquers, inks and wood stains.[1]
| [Synthesis]
2-Amino-5-nitrophenol is produced from 2-aminophenol by reaction with acetic anhydride to form 2-methylbenzoxazole, which is nitrated and hydrolysed to form 2-amino-5-nitrophenol.[2]
