Sulfur tetrafluoride is a chemical compound with the formula S F₄. It is a colorless corrosive gas that releases dangerous hydrogen fluoride gas upon exposure to water or moisture. Sulfur tetrafluoride is a useful reagent for the preparation of organofluorine compounds,^[3] some of which are important in the pharmaceutical and specialty chemical industries.
