Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of sulfonamide-based drugs with antimicrobial and anti-inflammatory properties. It serves as a building block in organic synthesis, enabling the introduction of sulfonyl groups into larger molecules. Its bromo substituent allows for further functionalization through cross-coupling reactions, making it valuable in medicinal chemistry for creating diverse compound libraries. Also employed in the preparation of kinase inhibitors and other biologically active agents.
