Feature product: MeFBSAA

N-Methyl-n-perfluorobutanesulfonylglycine (Methyl perfluorobutane sulfonamidoacetic acid; MeFBSAA) is a fluoroalkyl sulfonamide, belonging to the PFAS family. It was introduced as a replacement to perfluorooctanesulfonic acid (PFOS) and is used in paper and carpet treatments for water and stain resistance. High concentrations have been found in landfill leachate from discarded clothing and paper products treated with a PFAS. High concentrations have also been reported downstream from fluorochemical manufacturing facilities, in a river used as a source for drinking water.
