Used as an intermediate in the synthesis of high-performance polymers and specialty chemicals. Its functional carboxylic acid groups allow for esterification or amidation, making it valuable in creating polyesters, polyamides, and copolymers with enhanced thermal and mechanical properties. Also employed in the development of UV-absorbing materials due to the benzophenone core, contributing to light stability in coatings, plastics, and sunscreens. The monohydrate form aids in handling and solubility during industrial processes.
