Hi,

Just noticed that there are two entries for PFNS:

  • Perfluorononanesulfonic acid (PFNS) (chemcode: 68259-12-1)
  • Perfluorononanesulfonic acid (PFNS)(trace) (chemcode: 474511-07-4).

The first is PFNS in the CAS registry as PFNS (the sulfonic acid). I think the second is Perfluorononanesulfonate - i.e. a sulfonate not sulfonic acid).

Anyway worth noting - likely the Chem name needs changing?

Cheers
