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 complex molecules. Its bromo and methoxy functional groups allow for further chemical modifications through cross-coupling reactions, making it valuable in medicinal chemistry research. Also employed in the preparation of agrochemicals and bioactive molecules where sulfonamide moieties enhance target specificity and biological activity.
