This tetra ethyl ammonium fluoride serves as a catalyst for fluorine reactions such as oxidation, methylation, and deuteration. It is used as a catalyst for phase transitions in synthetic chemistry as well as a reagent for the breaking of Si-C bonds. This chemical compound is a white crystalline compound. To get rid of silyl ether protecting groups, employ TBAF as a source of fluoride in organic solvents. Additionally, it serves as a moderate base and a catalyst for phase transitions.
