  • Applications

    Disulfur decafluoride (CAS 5714-22-7) is a highly reactive fluorinating agent used to convert metal oxides and other inorganic substrates to fluorides, supporting processes in metallurgy, ceramics, and surface engineering. It also serves as a precursor or intermediate in the synthesis of fluorinated sulfur compounds and other specialty fluorinated chemicals. In electronics and semiconductor manufacturing, it appears in high-purity gas formulations as a reactive fluorine source for plasma etching and surface treatment. It is employed in research and development and pilot-scale production as a fluorinating reagent to access fluorinated intermediates and materials. Use is subject to local regulations and formulation limits.
