Used primarily as a key intermediate in the synthesis of fluorinated organic compounds, particularly in pharmaceutical and agrochemical industries. Its fluorosulfonyl group enables selective functionalization, making it valuable in the development of novel bioactive molecules. It serves as a building block in the preparation of sulfonamide-based drugs and is employed in research for designing enzyme inhibitors. Due to its reactivity, it is also utilized in radiofluorination studies for positron emission tomography (PET) tracer development.
