Sodium hexafluoroantimonate Usage And Synthesis

Uses

Sodium Hexafluoroantimonate (nasbf6) is a deeply processed fine chemical of antimony. It is widely used as catalyst in organic synthesis and photochemical reaction and additive for high-grade glass; Additives for high-grade UV curing coatings and inks, pharmaceutical intermediates, material intermediates, etc.
Especially in organic synthesis, it is usually used as a substitute for organic fluoride and is used in many scientific fields from pharmaceutical chemistry to material science. This is because pentavalent antimony forms a very solid coordination bond with fluorine ion, which makes fluorine a very stable state.
