Perfluorochemical (PFC) CAS Numbers
The resources on this page are intended to assist permittees in completing the Perfluorochemical Inventory Form.
In completing the PFC Inventory Form, some permittees may find it helpful to have a list of PFC names and CAS numbers. Below is a link that provides such information. Because there is such a vast number of PFCs that have been made and because each PFC may have different CAS numbers associated with it (for example: one CAS number for each salt of the PFC) the list below is not exhaustive. However, it is a helpful inventory tool.
If the list of CAS numbers is to be compared against a database, it should be compared against a total ingredient database or list, not an MSDS database. MSDS databases and lists do not include compounds that make up less than 1% of a product. Comparing the CAS list to an MSDS database or list could result in a PFC not being reported on the inventory form.

Description |
This PFC CAS list is compiled of CAS numbers provided by the U.S. Environmental Protection Agency and also from the August 2004 document Perfluorooctane Sulfonate (PFOS): Dossier prepared in support for a nomination of PFOS to the UN-ECE LRTAP Protocol and the Stockhom Convention, prepared by the Swedish Chemicals Inspectorate (KemI) and the Swedish EPA, Sweden. |
Definitions
Perfluorochemicals (PFCs) are a group of compounds made up of carbon chains in which all the carbon-hydrogen bonds have been replaced by carbon fluorine bonds. There are uniquely resistant to heat, oil, stains, grease and water. They do not degrade in the environment.
Fluorotelomers are compounds that are not technically perfluorinated, because not all of the carbon-hydrogen bonds are replaced with carbon-fluorine ones. But they have the potential to transform and produce PFCs. They are relatively small polymers and are used in surface treatment products to impart soil, stain, grease, and water resistance to carpets, textiles, paper, stone, and leather. They are used as high performance surfactants in products that must flow evenly, such as paints, coatings, and cleaning products, fire-fighting foams or the extremely thin engineering coatings used in semiconductor manufacturing.
CAS Number: CAS registry numbers are unique numerical identifiers generated by the Chemical Abstracts Service (CAS), a division of the American Chemical Society. Each chemical element, compound, polymer, biological sequence, mixture or alloy has a unique CAS number.
