Used primarily as a monomer and intermediate in the synthesis of high-performance polymers and polycarbonates. Its rigid aromatic structure and reactive hydroxyl groups make it suitable for creating thermally stable and mechanically strong engineering plastics. It is also employed in the development of specialty resins for coatings and adhesives that require resistance to heat and chemicals. Additionally, derivatives of this compound have been explored for use in electronic materials and as cross-linking agents in advanced polymer networks.
