Description

1-Octanesulfonic Acid, 3,3,4,4,5,5,6,6,7,7,8,8,8-Tridecafluoro-, Ammonium Salt is a high-purity, fluorinated anionic surfactant and electrolyte. Its unique perfluorinated alkyl chain combined with a sulfonate head group makes it an essential material for demanding applications requiring chemical resistance, thermal stability, and surface activity. This compound is primarily sought by manufacturers and researchers in the electronics, analytical chemistry, and specialty materials sectors.

Application

• Mobile Phase Additive for HPLC/UHPLC: Used as an ion-pairing reagent for the separation of highly polar and ionic compounds, particularly in reverse-phase chromatography.
• Electroplating & Surface Treatment: Acts as a wetting agent and leveler in fluorinated electrolyte baths for metal deposition and surface finishing processes.
• Lithium-Ion Battery Electrolytes: Serves as a functional additive to enhance electrolyte stability and interfacial properties on electrode surfaces.
• Polymerization Surfactant: Employed in emulsion polymerization, especially for fluorinated monomers, to produce high-performance polymers with improved properties.
• Fire-Fighting Foams (AFFF): A key fluorosurfactant component in aqueous film-forming foams used for hydrocarbon fuel fires.
• Coating & Ink Formulations: Provides superior wetting, leveling, and anti-cratering properties in high-performance fluoropolymer coatings and specialty inks.
