It appears to have a synonym Pentadecafluorooctanoic acid. Using that I found a hit on Thermo Fisher, but it doesn't have much additional information. FWIW, searching for "HF" in the document only comes up with:

decomposition can lead to release of irritating gases and vapors

Regardless of the date, I need to understand the reasoning behind any reclassification in order to assess correctly. Older information is still pertinent and quite honestly more helpful sometimes. I am not finding a good paper trail on this chemical.

What are the publishing dates of each? One may have new information

Subject: [DCHAS-L] Pentadecafluorooctanoyl chloride.

Has anyone worked with or know why the SDS from Sigma is drastically different than PubChem for
Pentadecafluorotoctanoyl chloride? Is this chemical a super acid like some fluoro compounds or is Sigma more correct?
