Naming Conventions and Physical and Chemical ... - PFAS

1 Naming Conventions and Physical and Chemical Properties of Per- and polyfluoroalkyl Substances ( pfas )1 IntroductionThe following topics are covered in this fact sheet: Polymer vs. Nonpolymer pfas Perfluoroalkyl substances polyfluoroalkyl substances PFAA Naming Conventions Long- chain vs. short - chain Linear vs. Branched Acid vs. Anion Replacement Chemistry Physical and Chemical PropertiesThis fact sheet uses three Conventions worth highlighting: Anionic form of Chemical names: Many pfas can exist in various ionic states (for example, acids, anions, cations), which has important implications for their Chemical and Physical properties. In most cases, this fact sheet uses the anionic form of a given pfas name, as this is the state in which most pfas exist in the environment.

Properties of Per- and Polyfluoroalkyl Substances (PFAS) 1 Introduction The following topics are covered in this fact sheet: • Polymer vs. Nonpolymer PFAS • Perfluoroalkyl substances • Polyfluoroalkyl substances • PFAA Naming Conventions • Long-Chain vs. Short-Chain • Linear vs. Branched • Acid vs. Anion • Replacement Chemistry

More recently, industry has developed and adopted alternative short-chain PFAS chemistries to replace long-chain PFAS. Many short-chain PFAS are structurally similar to their long-chain predecessors being replaced and are manufactured by the same companies. Publicly available health, toxicity, and hazard assessments of short-chain PFAS are limited.

Historically, the metal plating industry has used, and continues to use, per- and polyfluoroalkyl substances (PFAS) in some metal plating applications. Most notably, beginning in the 1980s, perfluorooctanesulfonic acid (PFOS) was used as a mist suppressant in hard and decorative chromium ... the formation of the short -chain perfluorocarboxylic ...

Shorter chain PFAS have been developed more recently to substitute the longer chain ones. In this context, an important distinction is the one between “long chain” and “short chain” PFAS6. The PFAS group includes also polymers: e.g. fluoropolymers7, perfluoropolyethers8 and side-chain fluorinated polymers9.
