Tetraethylammonium tetrafluoroborate is used as a phase transfer catalyst in organic synthesis. It finds application as an electrolyte additive in the capillary electrophoretic separation of polyphenols found in grape seed extracts. It is also used to prepare other tetrabutylammonium salts in aqueous solutions. It is involved in the synthesis of conducting poly(thiophenes).
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.
