Used primarily as a monomer in the production of high-performance polymers, especially in engineering plastics and specialty polyesters. It contributes to improved thermal stability and mechanical strength in polymer resins. Commonly found in coatings, adhesives, and electronic encapsulants due to its resistance to heat and chemicals. Also serves as an intermediate in the synthesis of liquid crystals and optical materials. Its symmetrical structure enhances crystallinity and durability in final products, making it valuable in automotive and electronic industries.
