Used primarily as an intermediate in organic synthesis, particularly in the production of polycarbonates and other specialty polymers. It serves as a carbonate-building block in reactions where controlled introduction of the carbonate group is required. Its aromatic structure enhances thermal stability in resulting polymers, making it suitable for high-performance materials. Also explored in the development of optical resins and electronic-grade coatings due to its clean reactivity and low volatility under processing conditions.
