CAS Number : 306-9-3

Description & Characteristics

Perfluoromethyldecalin , C11F20 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

    Perfluoromethyldecalin finds many applications including as a fluid for testing and cooling in the electronics industry, as a fluid for vapour phase sterilisation of medical equipment and various energy transfer applications.

    Safety, Handling and Storage

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