Used as an intermediate in the synthesis of high-performance polymers and resins, particularly in the production of specialty polyesters and polycarbonates. It contributes to improving thermal stability and mechanical strength of the resulting materials. Also employed in the development of crosslinking agents for coatings and adhesives, enhancing durability and chemical resistance. Its reactive hydroxyl groups allow for easy modification in organic synthesis, making it valuable in designing custom molecules for electronic and optical materials.
