Perfluorooctanesulfonic acid is an organofluorine compound. Salts of this compound are often used as surfactants. Like other fluorocarbons the C8F17 subunit in this compound repels water, and the sulfonic acid group makes the anion polar.
Additional recommended knowledge
Perfluorooctanesulfonic acid is usually used as the sodium or potassium salts, referred to as perfluorooctanesulfonates (PFOS).
Perfluorooctanesulfonates are persistent organic pollutants. It is exceptionally stable in the environment. In 1997, low levels of PFOS were found in tissues of polar bears, dolphins, albatrosses, and blood samples from people worldwide. PFOS is considered toxic through experiments done on rats.
