Used as a highly efficient arylating agent in organic synthesis, particularly for transferring the 4-fluorophenyl group under mild conditions. It is valuable in the preparation of biologically active compounds and pharmaceuticals where fluorinated aromatic rings enhance metabolic stability and binding affinity. Commonly employed in transition-metal-free arylation reactions, including C–H, O–H, and N–H functionalization, making it useful in drug discovery and materials science. Its stability and selectivity allow for precise incorporation of fluorinated aryl groups in complex molecules.
