Used as a key intermediate in the synthesis of high-performance polymers and resins, particularly in the production of specialty polyesters and polycarbonates. Its hydroxyl and ester functional groups enable cross-linking and enhance thermal stability, making it valuable in coatings, electronic materials, and flame-retardant additives. Also employed in the development of UV-curable systems due to its reactivity under radiation. Additionally, serves as a building block in pharmaceuticals and fine chemicals synthesis where aromatic rigidity and polarity are required.
