Used primarily as a specialized building block in organic synthesis, particularly in the development of pharmaceuticals and agrochemicals. Its reactive isothiocyanate group enables conjugation with amines to form thiourea derivatives, which are important in medicinal chemistry for designing bioactive molecules. The presence of both bromo and fluoro substituents allows for selective cross-coupling reactions, making it valuable in the construction of complex aromatic systems. It is also employed in the synthesis of fluorescent probes and labeled compounds for biochemical research due to its ability to modify proteins and peptides through selective covalent binding.
