Ammonium hexafluorophosphate (Cat No.:R044079) is an inorganic salt composed of an ammonium cation and a hexafluorophosphate anion. It appears as a white, crystalline solid and is highly soluble in polar organic solvents. This compound is widely used as an electrolyte component in electrochemical applications, including lithium-ion batteries and supercapacitors, due to its thermal stability and high ionic conductivity. Ammonium hexafluorophosphate also serves as a fluorinating agent and a source of PF₆⁻ in organometallic and coordination chemistry. Proper handling is essential, as it can release toxic hydrogen fluoride upon decomposition.
