2-nitrobenzoic acid

2-Nitrobenzoic acid (CAS 552-16-9), also known as o-nitrobenzoic acid, is an aromatic nitro compound used as a building block in the synthesis of pharmaceutical intermediates and specialty chemicals.

Where is 2-nitrobenzoic acid used?

• Pharmaceutical manufacturing: precursor
• Production of anthranilic acid derivatives, dyes, and active pharmaceutical ingredients requiring ortho-substituted benzoic acid frameworks
• Pigment and colorant producers: intermediate
• Synthesis of azo dyes and other chromophoric structures for textile and industrial coating applications
• Personal care formulations: preservation systems
• pH buffering where aromatic acid chemistry is required
• Specialty chemical manufacturers apply it in surface modification agents and wetting formulations where controlled acidity is needed.

Commercial specifications

• Bulk quantities in fiber drums or multi-layer bags
• Smaller packaging for laboratory and pilot-scale procurement
