Sulfur tetrafluoride, with the chemical formula SF₄, is an inorganic compound with a molecular weight of 108.059. At room temperature and pressure, sulfur tetrafluoride exists as a colorless gas, but has a strong pungent odor. The melting point and boiling point of this gas are relatively low, at -121℃and -40.4℃, respectively, which makes it easy to handle and store under certain conditions. However, sulfur tetrafluoride is highly toxic and is a non-flammable toxic gas that poses potential hazards to human health and the environment. It can invade the human body through inhalation, ingestion, etc., causing respiratory damage similar to phosgene, a dokonce i vedoucí k vážným důsledkům, jako je plicní edém .
