Used as an intermediate in the synthesis of high-performance polymers and specialty resins. Its amino and ester functional groups allow for step-growth polymerization, making it valuable in producing polyamides and polyurethanes with enhanced thermal stability and mechanical strength. Commonly applied in coatings, adhesives, and engineering plastics where durability and resistance to heat are required. Also explored in the development of fluorescent dyes and optical brighteners due to its aromatic structure and ability to undergo derivatization. Its solubility in organic solvents facilitates use in solution-based processing techniques.
