Application

3-Aminophthalic acid serves as a key precursor in the synthesis of fluorescent dyes, metal-organic frameworks (MOFs), and pharmaceutical intermediates. Its bifunctional carboxyl groups enable chelation with metal ions for catalytic or sensor applications. Researchers also employ it to modify polymer backbones for enhanced thermal or mechanical properties.
