Used as a reagent in organic synthesis, particularly in fluorination reactions. It serves as a source of the pentafluorosulfur (SF5) group, which is incorporated into various organic compounds to enhance their stability, lipophilicity, and bioactivity. Commonly applied in the development of pharmaceuticals, agrochemicals, and advanced materials. Its ability to introduce the SF5 group makes it valuable in creating compounds with unique properties for research and industrial applications.
