Used as an intermediate in the synthesis of biologically active compounds, particularly in the development of sulfonamide-based pharmaceuticals. It serves as a key building block in medicinal chemistry for creating potential antimicrobial, anti-inflammatory, and anticancer agents. The presence of bromo and nitro groups allows for further functionalization through cross-coupling reactions and nucleophilic substitutions, making it valuable in drug discovery and optimization. Also employed in research settings to design enzyme inhibitors and explore structure-activity relationships in sulfonamide derivatives.
