Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of sulfonamide-based drugs. It serves as a building block in medicinal chemistry for creating biologically active molecules, including potential antimicrobial and anti-inflammatory agents. Its bromo and ester functional groups allow for further chemical modifications, enabling coupling reactions and derivatization in drug discovery processes. Also employed in research settings for designing enzyme inhibitors and probing structure-activity relationships in sulfonamide libraries.
