Description

Heptadecafluorooctanesulfonic Acid Tetraethylammonium Salt is a high-purity perfluorooctanesulfonate (PFOS) derivative, serving as a critical reagent and standard in advanced material science and analytical chemistry. This compound is valued for its consistent performance as a surfactant, electrolyte, and reference material, enabling precise research and development. It is essential for industries and laboratories focused on fluoropolymer synthesis, electrochemistry, and environmental testing for per- and polyfluoroalkyl substances (PFAS).

Application

• PFAS Analytical Standard: Used as a certified reference material (CRM) for the quantification and identification of perfluorooctanesulfonic acid (PFOS) and related compounds in environmental, food, and biological samples via LC-MS/MS.
• Electrolyte Additive: Employed in lithium-ion battery and supercapacitor research to enhance electrolyte stability and interfacial properties.
• Fluoropolymer Synthesis: Acts as an emulsifier or surfactant in the emulsion polymerization of fluorinated monomers to produce high-performance materials like PTFE.
• Surface Modification: Utilized to create low-surface-energy, hydrophobic, and oleophobic coatings for textiles, electronics, and medical devices.
• Ion-Pairing Reagent: Serves in analytical chemistry as an ion-pairing agent for the separation of complex ionic mixtures in HPLC.
• Chemical Research: A key intermediate or model compound in studies investigating the environmental fate, transport, and remediation strategies for persistent organic pollutants (POPs).
