Used as a key intermediate in the synthesis of fluorinated pharmaceuticals and agrochemicals, where the presence of fluorine atoms enhances metabolic stability and bioavailability. It is also employed in the preparation of high-performance polymers, including polyimides and polyesters, offering improved thermal and oxidative resistance. Additionally, it serves as a building block in the development of liquid crystals and organic electronic materials due to its rigid aromatic structure and electron-withdrawing fluorine substituents.
