Used primarily as a monomer in the production of high-performance polyesters and liquid crystalline polymers. Its hydroxyl and ester functionalities enable it to participate in condensation polymerization, enhancing thermal stability and mechanical strength of the resulting materials. Commonly found in specialty plastics and fibers requiring resistance to heat and chemicals. Also utilized in coatings and adhesives where improved rigidity and durability are needed. Shows potential in optoelectronic applications due to its aromatic and planar structure facilitating charge transport.
