Tridecafluorohexanesulfonic acid potassium salt（Cat No.:R059206）is a perfluorinated sulfonic acid derivative, consisting of a six-carbon fluorinated alkyl chain fully substituted with fluorine atoms and a terminal sulfonate group neutralized by a potassium cation. This compound exhibits high chemical and thermal stability, as well as exceptional resistance to acids, bases, and oxidative conditions. It is commonly used as a surfactant, ionomer component, or additive in electrochemical applications, including fuel cells and fluoropolymer production. Its strong acidity and hydrophobic fluorinated chain also make it useful in surface treatments and environmental testing.
