| Hazard Information | Back Directory | [Description]
Perfluorooctanesulfonic acid or perfluorooctane sulfonate (PFOS), is a man-made fluorosurfactant and global pollutant. It is a very useful catalyst in chemical industry. It can catalyze the Intramolecular Hydroamination of Olefinic Sulfonamides in Fluorous Biphase System (FBS)1. It can also catalyze ring-opening reactions of methylenecyclopropanes with aromatic amines, sulfonamides and alcohols in supercritical carbon dioxide2. It is useful in the nitroaldol reaction in fluorous media, which is an important improvement of the chemo-selective addition of aldehyde3. | [Chemical Properties]
Perfluorooctane sulfonate can exist as a liquid or a powder. It is soluble in water (NTP, 2013). Perfluorooctane sulfonate has the ability to react with strong oxidizing agents. Upon decomposition, PFOS can form carbon oxides, sulfur oxides, and hydrogen fluoride. Additional information related to the physical and chemical properties of PFOS are not currently available. | [Application]
Heptadecafluorooctanesulfonic acid may be used as an analytical reference standard for the determination of the analyte in water samples using solid-phase microextraction combined with high-performance liquid chromatography with electrospray-ion trap mass spectrometry. | [Uses]
Perfluorooctane sulfonate (PFOS, 1-octanesulfonic acid, heptadecafluorooctanesulfonic acid, perfluorooctanesulfonic acid, 1-perfluorooctanesulfonic acid) is an eight-carbon compound in the perfluoroalkyl family of chemicals. Perfluorooctane sulfonate is used in a variety of applications, including textiles, leather products, cleaning products, and pesticides. Its main use was as a stain repellent on carpet, furniture, and other consumer products. 3M was the primary manufacturer of the chemical until it voluntarily phased it out in 2002 (USEPA, 2012). Perfluorooctane sulfonate is not manufactured any longer in the United States, but it can be imported for use in specific applications. | [Definition]
ChEBI: A perfluoroalkanesulfonic acid that is octane-1-sulfonic acid in which all seventeen of the hydrogens that are attached to carbons hvae been replaced by fluorines. | [General Description]
Heptadecafluorooctanesulfonic acid belongs to the class of perfluorinated alkyl acids and is emerging as persistent organic contaminants in the environment. | [Health effects]
Exposure to unsafe levels of PFOA/PFOS concentrations through drinking water may result in health effects including developmental effects to fetuses during pregnancy, cancer, liver effects, immune effects and thyroid effects. | [Environmental considerations]
Perfluorooctane sulfonic acid (PFOS) is one of a group of related chemicals known as perfluorinated alkylated substances (PFAS). These are also called perfluorochemicals (PFCs). This group of chemicals is commonly used in a wide range of industrial processes and is found in many consumer products. PFOS can enter groundwater from multiple sources, including sewage treatment plants, industrial sites, landfills, and places where it is used in firefighting foam such as airports, firefighter training sites, and military installations. Fish and shellfish can take up PFOS from water contaminated with the chemical. | [Toxics Screening Level]
The initial threshold screening level (ITSL) for perfluorooctanoic sulfonic acid (PFOS) is
0.0004 μg/m3 with 24-hour averaging time. | [References]
