2,5-Diaminoterephthalic acid（Cat No.:L038716）is an aromatic dicarboxylic acid derivative with amino groups positioned at the 2 and 5 positions of the benzene ring and carboxylic acids at the 1 and 4 positions. This unique substitution pattern imparts both acidic and basic functional sites, making it highly reactive for polymerization and complexation reactions. It serves as a key monomer in the synthesis of high-performance polyamides and polyimides, especially in materials requiring thermal stability and mechanical strength. Additionally, it is explored in coordination chemistry, dye production, and functionalized materials for electronic and optoelectronic applications.
