Potassium hexafluorophosphate (Cat No.: M079416) is an inorganic salt composed of potassium cations and hexafluorophosphate anions. This white, crystalline, and highly stable compound is widely used in electrochemistry as a supporting electrolyte due to its excellent solubility in polar organic solvents and chemical inertness. KPF₆ is also employed in the synthesis of organometallic complexes and ionic liquids. Its non-coordinating PF₆⁻ anion makes it ideal for stabilizing reactive cationic species, particularly in catalysis, battery research, and advanced material applications.
