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 for introducing the sulfonamide functional group into more complex molecules. Its bromo and methyl substituents allow for further functionalization through cross-coupling reactions, making it valuable in medicinal chemistry for drug discovery and optimization. Also employed in the preparation of enzyme inhibitors and receptor ligands due to the sulfonamide moiety's ability to interact with biological targets.
