Description

This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.

Applications
Tetra-n-butylammonium fluoride, 1M soln. in THF is used as a reactant for the preparation of triple monoamine reuptake inhibitors as a new generation of antidepressants, oligoribonucleotides with phosphonate-modified linkages, conjugated dienoic acid esters using Suzuki coupling reactions and polyacetylenic glucosides. It plays an important role in aryl alkyl alcohols through Nozaki-Hiyama allylation catalyzed by chiral bipyridyldiol ligands and chromium trichloride. It is also used as a catalyst for the silylation reactions. In addition, it is used as a source of fluoride ion in organic solvents as well as for the deprotection of silyl ether groups.

Solubility
Miscible with terahydrofuran, acetonitrile, dimethyl sulfoxide and organic solvents.

Notes
Store in a cool place. Hygroscopic. Keep the container tightly closed in a dry and well-ventilated place. Incompatible with oxidizing agents and oxygen.
