Used as an intermediate in the synthesis of functionalized polymers and specialty esters, particularly in the development of UV-absorbing coatings and optical brighteners. Its hydroxyl and ester groups enable cross-linking in resin formulations, enhancing durability and light stability. Also employed in the preparation of metal-organic frameworks (MOFs) due to its ability to coordinate with metal ions, offering potential in gas storage and catalysis applications. Additionally, serves as a building block in the design of biodegradable polyesters with improved thermal and mechanical properties.
