PFAS (per- and polyfluoroalkyl substances)
from sourceA class of everyday chemicals, not a product: the PFAS molecules MoleculeFinder holds.
From MoleculeFinder's PFAS list, each member checked against its formula: a fully fluorinated carbon chain, with at most one hydrogen and at least 2n - 1 fluorine atoms for n carbons.
Molecules in it 4
- Perfluorooctanoic acidC8HF15O2
On MoleculeFinder's PFAS list: 8 carbon and 15 fluorine atoms computed
PFOA, a fully fluorinated PFAS surfactant used in fire-fighting foams, paints, polishes, carpets and food-contact packaging.
As a pure substance: LD50 189 mg/kg (rat, other) from source
- Perfluorooctanesulfonic acidC8HF17O3S
On MoleculeFinder's PFAS list: 8 carbon and 17 fluorine atoms computed
PFOS, a PFAS surfactant once used in fire-fighting foams, floor polishes, metal plating and circuit-board etching. 3M phased it out by 2001.
As a pure substance: LD50 154 mg/kg (rat, oral) from source
- Perfluorononanoic acidC9HF17O2
On MoleculeFinder's PFAS list: 9 carbon and 17 fluorine atoms computed
PFNA, a nine-carbon PFAS surfactant used mainly as a processing aid in making fluoropolymers, and in fire-fighting foams and textile finishes.
As a pure substance, its GHS hazard label: signal word Danger; Corrosive, Irritant, Health hazard from source
- Perfluorohexanesulfonic acidC6HF13O3S
On MoleculeFinder's PFAS list: 6 carbon and 13 fluorine atoms computed
PFHxS, a six-carbon PFAS once used in fire-fighting foams and carpet stain and water repellents, phased out under US EPA rules.
As a pure substance, its GHS hazard label: signal word Danger; Corrosive, Irritant, Health hazard from source
