Used primarily as a key intermediate in the synthesis of pharmaceuticals and agrochemicals, this compound plays an important role in the preparation of fluorinated organic molecules. Its fluorosulfonyl group is highly reactive, making it valuable in sulfonylation reactions, particularly in the development of novel bioactive compounds. It is also employed in materials science for constructing functional polymers and in the design of specialty chemicals requiring high reactivity and selectivity. Due to its ability to introduce both fluorine and sulfonyl functionalities in a single step, it is favored in medicinal chemistry for structure-activity relationship studies and the optimization of drug candidates.
