Used as a key intermediate in the synthesis of functional polymers and specialty resins, particularly in the development of high-performance polyamides and polyimides. Its aromatic structure and reactive amino and ester groups enable strong thermal and chemical resistance in the final materials. Commonly applied in advanced coating systems, electronic encapsulants, and aerospace components where durability at elevated temperatures is required. Also explored in controlled drug delivery systems due to its biocompatibility and tunable degradation properties when incorporated into biodegradable polymer matrices.
