Widely used in organic synthesis as a sulfonylation agent, particularly in the preparation of sulfonamides with potential pharmaceutical activity. Its structure allows for selective derivatization in drug discovery, especially in the development of bioactive molecules targeting enzymes and receptors. The presence of both bromo and fluoro substituents enables further functionalization via cross-coupling reactions, making it a valuable intermediate in medicinal chemistry. Commonly employed in the synthesis of protease inhibitors and other therapeutic agents where sulfonyl chloride groups act as key pharmacophores. Also utilized in agrochemical research for building complex molecules with enhanced stability and biological activity.
