Used as an intermediate in the synthesis of biologically active sulfonamide derivatives, particularly in pharmaceutical research. It serves as a building block for developing potential antimicrobial, anti-inflammatory, and anticancer agents. The presence of both bromo and methoxy groups allows for further functionalization via cross-coupling reactions, making it valuable in medicinal chemistry for structure-activity relationship studies. Also employed in the preparation of receptor ligands and enzyme inhibitors due to the sulfonamide moiety's affinity for various biological targets.
