  • Applications

    Sulfur tetrafluoride, CAS 7783-60-0, is primarily used as a fluorination agent in organic synthesis to introduce fluorine into substrates, enabling the production of organofluorine intermediates important for pharmaceutical and agrochemical development. It is also employed in the synthesis of fluorinated polymers and specialty materials to enhance chemical resistance and thermal stability. In electronics and semiconductor manufacturing, SF4 is used as a fluorination/etching gas to process and modify surfaces of silicon-containing materials. It also has applications in coatings and adhesives to improve wear and corrosion resistance. In research and industrial production, SF4 serves as a reagent for preparing fluorinated derivatives, subject to local regulations and formulation limits.
