Used in the synthesis of functional polymers and resins due to its reactive carboxylic acid groups and allyl ether functionality. The compound serves as a monomer in producing specialty polyesters and copolyesters with enhanced thermal and mechanical properties. Its allyl group allows for further crosslinking or modification via radical reactions or click chemistry, making it valuable in coatings, adhesives, and network polymers. Also employed in the development of metal-organic frameworks (MOFs) where the rigid aromatic core and coordinating acid groups help form structured porous materials. Additionally, it acts as an intermediate in creating plasticizers and UV-curable systems.
