Tracking categories (test):
6:2-fluorotelomersulfonic acid (6:2-FTS) is a chemical compound that belongs to the group of fluorotelomersulfonic acids within the broader class of per- and polyfluorinated alkyl compounds (PFAS). Due to its structural similarity to perfluorooctanesulfonic acid (PFOS), it is also called H 4 PFOS .[2]
Production
6:2-Fluorotelomersulfonic acid is produced via telomerization. In addition, it is also formed, for example, from some perfluorocarboxybetaines after their splitting.[3]
Usage
6:2-Fluorotelomersulfonic acid and its derivatives are used as a replacement product for perfluorooctanesulfonic acid (PFOS) or its salts in fire-fighting foams.
