Uses
Dyestuff intermediate. Acetylation of 3-nitroaniline followed by reduction gives 3-aminoacetanilide. Diazotization, followed by reduction of the diazosulfonate with ammonium bisulfite and subsequent hydrolysis, gives (3-nitrophenyl) hydrazine; an intermediate in the production of pyrazolone azo coupling components. 3-Nitroaniline is used as a diazo component (Fast Orange R Base) in azo dyes (e.g., C.I. Disperse Yellow 5 and C.I. Acid Orange 18). 3-Nitroaniline is commonly used as a raw material for dyes. It is also used as a chemical intermediate for azo coupling component 17 and the dyes disperse yellow 5 and acid blue 29. The chemical is changed to other substances (dyestuffs and m-nitrophenol) during the dyeing process.
