Used as an intermediate in the synthesis of pharmaceuticals, 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 3-bromo-4-methylbenzenesulfonyl group, which can enhance the biological activity or stability of target molecules. Also employed in the preparation of agrochemicals and functional materials where sulfonyl derivatives are required. Its bromo functionality allows for further cross-coupling reactions, enabling the construction of more complex molecular architectures.
