Sulfur Tetrafluoride (SF4) is a special gas that plays an important role in specific industrial applications and scientific research fields. Due to its unique chemical properties, sulfur tetrafluoride gas is often used in fluorination reactions in organic synthesis and other processes that require high specificity. For customers seeking high-purity or special specifications of sulfur tetrafluoride (SF4 Specialty Gas), finding a reliable supplier is the key to ensuring smooth experiments or production.
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. The associated bond distances are S–F ax = 164.3 pm and S–F eq = 154.2 pm. Weak axial ligand bonding in high-valent molecules is typical. Compared with SF4, the related molecule SF 6 has sulfur in the 6+ state, and no valence electrons remain unbonded to the sulfur, so the molecule adopts a highly symmetrical octahedral structure. In further contrast to SF4, SF 6 is chemically very inert.
The 19 F NMR spectrum of SF 4 shows only one signal, indicating that the positions of axial and equatorial F atoms are rapidly interconverted by pseudo-rotation.
■ Sulfur tetrafluoride has limited practical applications due to its toxic and corrosive nature. However, it can be used as a fluorinating agent in organic chemistry reactions, where it can replace hydrogen atoms with fluorine atoms in organic molecules.

■ It is also used as an electron gas in certain etching processes in the semiconductor industry.
Sulfur tetrafluoride is highly toxic and corrosive, and it should be handled with extreme caution. Proper protective equipment and safety measures, including good ventilation and appropriate personal protective gear, are essential when working with this compound. It is advisable to consult safety data sheets and follow all relevant safety guidelines and regulations when using SF4.
