| Hazard Information | Back Directory | [Definition]
ChEBI: A perfluoroalkanesulfonic acid that is hexane-1-sulfonic acid in which all thirteen of the hydrogens that are attached to carbons have been replaced by fluorines. | [Chemical Properties]
Perfluorohexane sulfonate (PFHxS, perfluorohexane sulfonic acid, perfluorohexane-1-sulphonic acid) is slightly soluble in water. Perfluorohexane sulfonate has the ability to react with strong oxidizing agents. Upon decomposition, PFHxS can form carbon monoxide, carbon dioxide, hydrogen fluoride, and oxides of sulfur. Additional information related to the physical and chemical properties of PFHxS are not currently available. | [Uses]
Perfluorohexane sulfonate is a six-carbon compound in the perfluoroalkyl family of chemicals. Perfluorohexane sulfonate was once used in firefighting foam and carpet treatment solutions. It was once widely used by 3M as a stain and water repellent but was phased out due to U.S. Environmental Protection Agency regulations. Much like other perfluoroalkyls, PFHxS can persist in the environment. |
