Pharmaceutical Intermediate

Important amino-nitro substituted benzoic acid building block, widely used in synthesis of anti-inflammatory, analgesic and heterocyclic drugs; can undergo reduction, diazotization and cyclization for drug skeleton construction.

Dye & Pigment Intermediate

Key raw material for azo dyes, metal complex dyes and organic pigments, applied in diazotization-coupling reactions to produce colorants with stable shade and fastness.

Agrochemical Intermediate

Used for synthesis of fungicides, herbicides and plant growth regulators, providing good biological activity and structural modifiability.

Organic Synthesis Building Block

Commonly used in custom fine chemical synthesis for preparing substituted aromatic derivatives and heterocyclic intermediates.

Laboratory Research Reagent

Used as standard intermediate for organic synthetic route exploration and medicinal chemistry structure-activity relationship research.
