Used as an intermediate in the synthesis of biologically active compounds, particularly in the development of pharmaceutical agents targeting inflammatory and neurological disorders. Its sulfonyl chloride group enables easy derivatization to form sulfonamides, which are common motifs in drug design. It is also employed in the preparation of enzyme inhibitors due to its ability to interact with specific protein targets. Additionally, it serves as a building block in combinatorial chemistry for generating compound libraries used in high-throughput screening.
