It has an irreplaceable position in the production of fine chemicals, liquid crystal materials and high-end pharmaceutical industries. Product Description CAS NO  7783-60-0 UN NO  2418 EINECS NO  232-013-4 Molecular weight  108.06 Appearance  Colorless Melting point  −121.5~−120.5℃ Boiling point  −40.4℃ Density  1.95g/m DOT Class  2.3+8 Label  Toxic Gas, Corrosives Sulfur tetrafluoride Gas is a colorless gas with a distinct sulfurous odor. It is highly toxic by inhalation and is highly irritating to the skin, eyes and mucous membranes. It reacts violently with water and acids, producing toxic fluoride and sulfur oxide fumes and acidic solutions. Sulfur tetrafluoride is heavier than air. The sulfur in SF4 is in the formal +4 oxidation state. Sulfur has a total of six valence electrons, two of which form lone pairs. Therefore, the structure of SF4 can be predicted using the principles of VSEPR theory: it is a seesaw shape with the S at the center. One of the three equatorial positions is occupied by non-bonding lone pair electrons. Therefore, this molecule has two different types of F ligands, two axial and two equatorial.
