Tetrabutyl Ammonium Fluoride

TBAF — premier fluoride source for selective silyl ether deprotection and phase transfer reactions.

Tetrabutyl ammonium fluoride (TBAF) is an indispensable reagent in organic and medicinal chemistry, celebrated as the reagent of choice for cleaving silyl protecting groups (such as TBS, TBDPS, TMS and TIPS) under mild conditions. It is also used as a nucleophilic fluoride source, a mild base in carbon-carbon bond forming reactions, and as a phase transfer catalyst. Form (hydrate/solution), assay and packaging are confirmed against each enquiry.
