This compound group is specific to the Stockholm Convention on Persistent Organic Pollutants (POPs)
According to decision SC-12/12 "Long-chain perfluorocarboxylic acids, their salts and related compounds" means the following:
(1) Long-chain perfluorocarboxylic acids or their salts, for the purposes of the Convention, are a homologous series of substances with the molecular formula of CaF2+1COOH (where 8 ≤ n ≤ 20);
(ii) Compounds related to long-chain perfluorocarboxylic acids, for the purposes of the Convention, are any substance that is a precursor and may transform to long-chain perfluorocarboxylic acids, where the perfluorinated alkyl moiety has the formula CF2n+1 (where 8 ≤ n ≤ 20) and is directly bonded to any chemical moiety other than a fluorine, chlorine or bromine atom.
The following compounds are not included as long-chain perfluorocarboxylic acids, their salts and related compounds: perfluorooctanoic acid (PFOA), its salts and PFOA-related compounds as listed in Annex A to the Convention."
