Application

4-Bromo-3-fluorophenol serves as a versatile synthon in medicinal chemistry for constructing kinase inhibitors and PET radiotracer precursors. The fluorine moiety enhances bioavailability in drug candidates, while the bromine allows for palladium-catalyzed cross-coupling reactions. It is also employed in material science as a monomer for flame-retardant polymers and in ligand design for transition metal catalysts.
