Potassium heptadecafluoro-1-octanesulfonate CAS#2795-39-3

Products Description of Potassium heptadecafluoro-1-octanesulfonate CAS#2795-39-3

Potassium perfluorooctanesulfonate (PFOS-K, CAS 2795-39-3) is an organofluorine surfactant widely used in industrial applications due to its exceptional chemical stability and surface-active properties. As the potassium salt of perfluorooctanesulfonic acid (PFOS), it serves as a key ingredient in chromium mist suppression during electroplating, where it forms stable foam layers to minimize toxic acid mist emissions, while also functioning as a wetting agent and firefighting foam additive (fluoroprotein type). Its molecular structure – featuring a fully fluorinated 8-carbon chain and sulfonate group – grants both hydrophobic and oleophobic characteristics. However, its environmental persistence and bioaccumulation potential have led to strict international regulations under the Stockholm Convention on Persistent Organic Pollutants, with permitted use currently limited to specific industrial applications where alternatives are unavailable. Proper handling requires sealed containers (typically 25kg drums) and avoidance of high-temperature decomposition (>300°C) to prevent hazardous byproducts.
