It is commonly used in cyclic voltammetry electroanalytical studies batteries and electrosynthesis. It is also used in research involving electron-transfer reactions and electrochemical characterization of chemical compounds.

it is mainly used as a supporting electrolyte to increase the ionic conductivity of non-aqueous solutions. It helps maintain stable electrical conditions during electrochemical experiments.

Tetrabutylammonium hexafluorophosphate is a quaternary ammonium salt usually available as a white crystalline solid. It is soluble in many organic solvents and has a weakly coordinating hexafluorophosphate ion.
