Synonyms: Perfluoromethylcyclohexane

CAS Number : 355-02-2

Description & Characteristics

Perfluoromethylcyclohexane, C7F14 is a fully-fluorinated, odourless, colourless liquid with the following characteristics:

  • Compatibility with most construction materials
  • Excellent chemical and thermal stability
  • Non flammability
  • Practically non-toxic1
  • Applications

    Perfluoromethylcyclohexane finds many applications as a fluid for use in the electronics industries for testing and direct contact cooling.

    Safety, Handling and Storage

    Although Perfluoromethylcyclohexane is considered biologically and chemically inert, good laboratory practice should be observed when handling. Perfluoromethylcyclohexane has an indefinite shelf life if properly stored in its original sealed container. Safety data sheets are available on request.
