Used primarily as an intermediate in the synthesis of pharmaceuticals and agrochemicals. Its sulfonyl chloride group readily reacts with amines and alcohols, making it valuable for forming sulfonamides and sulfonate esters—key structural motifs in drug development. Commonly employed in the preparation of kinase inhibitors and other biologically active compounds. Also utilized in materials science for modifying polymers and creating specialty chemicals with enhanced stability or reactivity. The bromo and fluoro substituents allow further functionalization via cross-coupling reactions, enabling complex molecule construction in multi-step organic syntheses.
