Application

Sodium tetrafluoroborate may be used as a catalyst for the synthesis of bis(indolyl)methanes via electrophilic substitution reaction of indoles with aldehydes and ketones. It may also be used as a source of tetrafluoroborate anoins during the synthesis of ionic liquids like 1-butyl-3-methylimidazolium tetrafluoroborate and trihexyl(tetradecyl)phosphonium tetrafluoroborate.

Sodium tetrafluoroborate may be used for the laboratory synthesis of boron fluoride. It may be used for the synthesis of fluoro-nucleic acids and fluoroheterocyclic compounds.

General description

Sodium tetrafluoroborate (NaBF4) is colorless sodium salt and its crystals belong to the rhombic crystal system. It can be synthesized by reacting tetrafluoroboric acid with sodium carbonate or hydroxide.
