2-chloro-4-nitroaniline

2-Chloro-4-nitroaniline (CAS 121-87-9) is an aromatic amine intermediate used primarily in the synthesis of azo dyes and pigments.

Where is 2-chloro-4-nitroaniline used?

• Textile dyeing: diazotized and coupled to produce azo dyes that deliver strong, wash-resistant color on cotton and synthetic fibers
• Printing inks and packaging coatings: yellow and orange azo pigments
• Industrial paints and coatings: durability
• Leather and paper: colorant formulations with consistent hue and substrate compatibility
• Pharmaceutical manufacturing: building block for active intermediates
• The chloro and nitro substituents provide selective reactivity for further functionalization in organic synthesis and medicinal chemistry.

Commercial specifications

• Purity typically 98% to 99%+ for synthesis-grade applications
• Pharmaceutical-grade material meeting tighter impurity specifications from select suppliers
