Aplicaciones

Tetra-n-butylammonium fluoride trihydrate is used as a phase transfer catalyst, as a mild base and as a source of fluoride ion in organic solvents. It is also used as a deprotecting agent to remove silyl ether protecting groups. It acts as a reactant for the preparation of deprotecting agents, in preparation of cellulose derivatives, lipophilic peptides for DNA transfections in vivo and Dehydrobromination reactions. It plays an important role in the convertion of O-silylated enolates in to carbonyls in the presence of dimethyl sulfoxide.

Notas

Hygroscopic. Keep the container tightly closed in a dry and well-ventilated place. Incompatible with strong oxidizing agents.
