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, antiviral, and enzyme inhibitory properties. The presence of bromine allows for further functionalization via cross-coupling reactions, making it valuable in medicinal chemistry for developing new drug candidates. Also utilized in the preparation of kinase inhibitors and other targeted therapies in oncology research.
