Used as an intermediate in organic synthesis, particularly in the development of pharmaceuticals and agrochemicals. Its sulfonamide structure makes it valuable in the preparation of bioactive molecules, including potential antimicrobial and anti-inflammatory agents. The bromine substituent allows for further functionalization via cross-coupling reactions, such as Suzuki or Heck reactions, enabling the construction of complex aromatic systems. It is also employed in the synthesis of sulfonamide-based receptor ligands and enzyme inhibitors, where the N-phenyl and N-butyl groups contribute to lipophilicity and target binding affinity.
