Used as an intermediate in the synthesis of sulfa drugs, particularly in the development of antibacterial agents. Its reactive bromoacetyl group allows for easy conjugation with nucleophiles, making it valuable in medicinal chemistry for building more complex sulfonamide derivatives. Commonly employed in the preparation of enzyme inhibitors, especially carbonic anhydrase inhibitors, due to the strong affinity of sulfonamides for zinc-containing active sites. Also utilized in biochemical research for labeling or modifying proteins and peptides through covalent attachment. Its structural features support use in creating targeted pharmaceuticals with enhanced binding and selectivity.
