Perfluorooctanesulfonamide

Description:

Perfluorooctanesulfonamide (PFOSA) is a synthetic organic compound belonging to the class of perfluoroalkyl substances (PFAS). It is characterized by a long carbon chain, specifically an octane backbone, fully fluorinated, with a sulfonamide functional group. PFOSA is known for its high thermal and chemical stability, which makes it resistant to degradation in the environment. This compound is typically used as a surfactant and is associated with various industrial applications, including in the production of water- and oil-repellent coatings. Due to its persistent nature, PFOSA has raised environmental and health concerns, as it can accumulate in living organisms and has been detected in various environmental matrices, including water and soil. Toxicological studies suggest potential adverse effects, including endocrine disruption and developmental toxicity. Regulatory agencies are increasingly scrutinizing PFAS compounds, including PFOSA, leading to efforts aimed at reducing their use and mitigating their environmental impact. Overall, PFOSA exemplifies the challenges posed by persistent organic pollutants in modern chemistry and environmental science.

CAS: 754-91-6

Perfluorooctanesulfonamide (PFOS) is an organic compound that is used as a surfactant in fire-fighting foams and metalworking fluids. PFOS is highly toxic to humans and animals, and it can persist for long periods of time in the environment. It has been shown to inhibit the activity of several enzymes, including carboxylesterase, acetylcholinesterase, and butyrylcholinesterase, which are essential for proper functioning of the liver cells. PFOS also inhibits the oxidation of fatty acids by hydroxyl radicals in vitro, leading to lipid peroxidation. Furthermore, PFOS has been shown to be carcinogenic in animal studies. The degradation process for PFOS includes hydrolysis by esterases or glucuronidases and oxidation by cytochrome P450 enzymes or glutathione reductase.
