Application

1-Bromo-2,3-difluorobenzene serves as a versatile intermediate in organic synthesis, particularly for constructing fluorinated aromatic systems in drug discovery. The electron-withdrawing fluorine atoms facilitate regioselective functionalization, making it valuable for developing kinase inhibitors and PET radiotracers. In materials science, it’s employed to synthesize liquid crystals and fluorinated polymers with enhanced thermal stability. The compound’s orthogonal reactivity enables sequential derivatization of both the bromine and fluorine substituents.
