Description
Tetrabutylammonium hexafluorophosphate (TBAPF6), CAS 3109-63-5, is a quaternary ammonium salt. It is composed of a tetrabutylammonium cation () and a hexafluorophosphate anion (). This compound is highly valued in electrochemistry as a supporting electrolyte, particularly for non-aqueous systems. Its popularity stems from its excellent solubility in a wide range of organic solvents, a broad electrochemical window (meaning it doesn’t easily oxidize or reduce), good thermal stability, and the relatively inert nature of the hexafluorophosphate anion. These characteristics allow for the study of electrochemical processes over a wide potential range with minimal interference from the electrolyte itself. While primarily a laboratory chemical for research and industrial electrochemical applications, it is not typically considered a “pharmaceutical product” for direct therapeutic use but may be employed in the electrochemical synthesis or analysis of pharmaceutical substances.
