Perfluorohexane (C6F14), or tetradecafluorohexane, is a fluorocarbon. It is a derivative of hexane in which all of the hydrogen atoms are replaced by fluorine atoms. It is used in one formulation of the electronic cooling liquid/insulator Fluorinert for low-temperature applications due to its low boiling point of 56°C and freezing point of −90°C. It is odorless and colorless. Unlike typical hydrocarbons, the structure features a helical carbon backbone.
