CAS 16950-06-4

Hexafluoroantimonic acid

Description:

Hexafluoroantimonic acid, with the CAS number 16950-06-4, is one of the strongest known superacids, surpassing even sulfuric acid in acidity. It is a colorless, highly corrosive liquid that is a combination of antimony pentafluoride and hydrogen fluoride. This acid is characterized by its ability to protonate even weak bases, making it a powerful reagent in organic synthesis and catalysis. Its extreme acidity is attributed to the stability of the resulting anion, which is formed upon protonation. Hexafluoroantimonic acid is typically handled with extreme caution due to its corrosive nature and potential to cause severe chemical burns. It is often stored in specialized containers to prevent reactions with moisture or other substances. In addition to its use in chemical research, it has applications in the production of fluorinated compounds and in the field of materials science. Due to its hazardous properties, proper safety protocols must be followed when working with this substance.

Hexafluoroantimonic Acid

CAS: 16950-06-4

Hexafluoroantimonic acid (HFA) is a hydroxy group-containing compound that can be used as a fluorescence probe. HFA is used in the synthesis of polymers and in the production of cationic polymerization initiators, which are compounds that initiate the polymerization of monomers. It reacts with hydrogen fluoride to form hexafluorophosphoric acid and hexafluoroacetic acid. Hexafluoroantimonic acid has been shown to have biodegradable properties and is not toxic to humans or plants. However, it does cause environmental pollution through its ability to deplete ozone.
