Description

n-Ethyl-1,1,2,2,3,3,4,4,5,5,5-Undecafluoro-n-[2-(Phosphonooxy)Ethyl]Pentane-1-Sulphonamide is a high-value, multi-functional fluorinated organosulfur compound with a phosphonooxyethyl side chain. This unique molecular architecture, combining perfluorinated, sulfonamide, and phosphate ester functionalities, makes it a critical intermediate for advanced material synthesis. It is essential for R&D and production in industries requiring specialized surfactants, surface modifiers, and high-performance polymer additives. The compound is supplied under strict quality control to ensure batch-to-batch consistency for demanding applications.

Application

• Fluorinated Surfactant & Wetting Agent Precursor: Serves as a key building block for synthesizing next-generation fluorosurfactants with exceptional spreading and leveling properties for coatings, films, and electronic materials.
• Surface Modification & Anti-fouling Coatings: Used to create low-surface-energy coatings that provide water, oil, and stain repellency for textiles, membranes, and industrial surfaces.
• Fire-Resistant (FR) Polymer Additive: The phosphorus and fluorine content contributes to flame retardancy, making it a valuable monomer or additive for engineering plastics and specialty resins.
• Lithium-Ion Battery Electrolyte Additive: Potential use in formulating advanced electrolyte systems to improve battery cycle life, safety, and high-voltage stability.
• Pharmaceutical & AgroChemical Intermediate: Acts as a sophisticated synthon for introducing fluorinated and phosphonated motifs into bioactive molecules to alter their metabolic stability and binding properties.
• Paper & Fiber Treatment: Imparts oil and grease resistance to specialty papers, packaging, and non-woven fabrics.

Storage

Preserve in a tightly closed container, protected from light. This material is hygroscopic (moisture-sensitive) and must be stored in a cool, dry place with controlled humidity. Recommended storage temperature is 2°C to 8°C (refrigerated) for long-term stability. Allow the sealed container to reach ambient temperature before opening to prevent moisture condensation. Store away from strong bases and oxidizing agents.
