Synonyms: Perfluoroperhydrophenanthrene

CAS Number : 306-91-2

Description & Characteristics

Perfluoroperhydrophenanthrene,C14F24, is a fully-fluorinated, odourless, colourless, non-volatile liquid with the following characteristics:

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

    Perfluoroperhydrophenanthrene finds many applications as a fluid for use in the electronics industries, including vapour phase soldering, condensation inert heating, fluid for testing and direct contact cooling.

    Safety, Handling and Storage

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