Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of kinase inhibitors for cancer treatment. It serves as a building block in medicinal chemistry due to its sulfonyl group, which enhances binding affinity to biological targets. Also employed in research settings to design sulfonamide-based bioactive molecules with potential anti-inflammatory and antimicrobial properties. Its bromo substituent allows for further functionalization via cross-coupling reactions, making it valuable in structure-activity relationship studies.
