Application

4,4′-Difluorodiphenyl sulfone serves as a key monomer in synthesizing polyethersulfone (PES) polymers, widely used in high-temperature membranes and medical devices due to its thermal stability. It acts as a precursor in pharmaceutical intermediates, particularly for fluorine-containing bioactive molecules. The compound is also employed in liquid crystal polymers (LCPs) and as a crosslinking agent in specialty resins for aerospace applications.
