Used as a key intermediate in the synthesis of high-performance polymers, particularly in the production of polyesters and polyamides with enhanced thermal and mechanical properties. Its dihydroxy and diester functionalities allow for controlled polymerization, improving chain rigidity and crystallinity. Also employed in the development of functional materials for optical and electronic applications due to its ability to form stable, ordered structures. Additionally, it serves as a building block in the preparation of metal-organic frameworks (MOFs) where its hydroxyl groups can coordinate with metal ions to form porous networks useful in gas storage or catalysis.
