Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the production of fluoro-substituted drugs where enhanced metabolic stability and bioavailability are desired. Its structure supports the development of active ingredients in anti-inflammatory and central nervous system medications. Also employed in the preparation of high-performance polymers, offering improved thermal and oxidative resistance, making it suitable for engineering plastics and specialty resins. Additionally, it serves as a building block in organic electronics and liquid crystal materials due to its rigid aromatic framework and electron-withdrawing properties.
