Used primarily as a monomer in the production of specialty polyesters and copolyesters, this compound contributes to the development of high-performance polymers with enhanced thermal stability and mechanical strength. It is especially valuable in creating resins for industrial coatings, films, and engineering plastics where resistance to heat and chemicals is required. Its structural rigidity improves the glass transition temperature of resulting polymers, making them suitable for demanding applications in electronics and automotive components. Additionally, it serves as an intermediate in the synthesis of advanced organic materials and liquid crystals.
