3-Nitroaniline is an aromatic amine with a nitro group attached to a benzene ring, widely used as an intermediate in the synthesis of dyes, pharmaceuticals, and agrochemicals, including azo pigments (as the diazo component Fast Orange R Base) and 3-nitrophenol, which is prepared from it by diazotization. It appears as an orange to yellow crystalline solid with a melting point of 114–116°C and limited solubility in water. This chemical has a CAS number of 99-09-2, a molecular formula of O2NC6H4NH2, and a molecular weight of 138.12 g/mol. It must be stored at ambient conditions but requires careful handling due to its Danger classification, including potential toxicity and environmental hazards. Molekula supplies 3-Nitroaniline from research to bulk quantities with full documentation and ISO 9001:2015 traceability.
