* N/A= Not Applicable as non phase-in substances, they do not have legally binding EC numbers.

Capstone™ Products exist as substances and polymers. The polymers themselves are not subject to registration and therefore their SDS include neither registration numbers nor exposure sceanrios for these monomers.

Some Capstone™ Products may be considered mixtures and may also contain substances and monomers which have a 2018 registration deadline.

These products may also contain substances for which Chemours is considered a Downstream User (DU). More information on the registration status of these substances (registration numbers, uses, etc.) are communicated in our SDS.


2. The following Capstone™ Products have been registered under the REACH legislation as a transported isolated intermediate under Strictly Controlled Conditions (SCC).


Substance/Monomer CAS # EC #
1,1,1,2,2,3,3,4,4,5,5,6,6-tridecafluoro-8-iodooctane 2043-57-4 218-056-1
3,3,4,4,5,5,6,6,7,7,8,8,8-tridecafluorooctan-1-ol 647-42-7 211-477-1
N-[3-(dimethylamonio)propyl]-3,3,4,4,5,5,6,6,7,7,8,8,8-tridecafluoro-a-octanesulfonamide 34455-22-6 608-993-8
3,3,4,4,5,5,6,6,7,7,8,8,8-tridecafluorooctanesulphonyl chloride 27619-89-2 248-576-4

To allow continued delivery after registration of an intermediate under Strictly Controlled Conditions (SCC), Chemours as supplier has already obtained written SCC confirmations from current first line customers, and informed them that they are also required to confirm SCC if the intermediate is subsequently sold to another party.

If you are interested in this product and are not currently a Chemours customer, please contact the corresponding Chemours area sales representative, or complete our SCC template and contact us.
