Used as an intermediate in the synthesis of biologically active compounds, particularly in pharmaceutical research. It serves as a building block for sulfonamide-based drugs, which are known for their antimicrobial, anti-inflammatory, and anticancer properties. The presence of bromine allows for further functionalization via cross-coupling reactions, enabling the development of diverse compound libraries for drug discovery. Also employed in the preparation of kinase inhibitors and other targeted therapies in medicinal chemistry.
