Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of nonsteroidal anti-inflammatory drugs (NSAIDs) and selective COX-2 inhibitors. Its structure allows for effective derivatization, enabling the formation of esters, amides, and other functional groups important in drug design. Commonly employed in medicinal chemistry for structure-activity relationship (SAR) studies due to the presence of both electron-withdrawing bromo and sulfonyl groups, which influence binding affinity and metabolic stability. Also utilized in the preparation of biologically active molecules targeting cancer and inflammatory diseases.
