Description
Tetraethylammonium tetrafluoroborate (TEATFB), CAS 429-06-1, is a quaternary ammonium salt composed of four ethyl groups attached to a central nitrogen atom (tetraethylammonium cation, ) and a tetrafluoroborate anion (). Similar to its tetrabutyl counterpart, TEATFB is a widely used supporting electrolyte in electrochemical studies, particularly in non-aqueous solutions. It provides good solubility in polar organic solvents, a broad electrochemical window, and reasonable ionic conductivity, making it suitable for a variety of electrochemical techniques. While less soluble in highly non-polar solvents compared to TBATFB, TEATFB offers advantages in certain applications due to its different solvation properties and ion pairing characteristics. It is typically a white crystalline solid. Although primarily a laboratory and industrial chemical, it is crucial for electrochemical research that may contribute to advancements in pharmaceutical analysis and synthesis.
