Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of anti-inflammatory and analgesic agents. Its structure allows for efficient derivatization, making it valuable in medicinal chemistry for constructing biologically active molecules. The fluorosulfonyl group is highly reactive, enabling selective modifications in drug design. It is also employed in the preparation of covalent inhibitors, where it acts as an electrophilic warhead that binds irreversibly to target proteins. Additionally, it finds use in agrochemical research for creating novel herbicides and plant growth regulators.
