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.
Perfluorohexane is considered biologically inert and chemically stable. It is one of the Fluorinert brand solvents/coolants. It is used as a solvent and coolant. In medical imaging it is used as a contrast agent.
