Anwendungen · 1 Eintrag

VerwendenTetrabutylammonium fluoride (TBAF) is a commonly used organic soluble fluoride salt. It is used as a base, a phase transfer catalyst, and as a fluoride source. In the research field of fluoride sensor development, TBAF is used as an easy to handle and measurable fluoride anion source. The fluoride in TBAF, once dissolved, can be thought of as a free fluoride with little interaction with the ammonium cation. Since TBAF should not absorb light at wavelengths greater than 240nm, it is useful to monitor sensing reactions with visible spectroscopy.
