Description

n-Ethyl-1,1,2,2,3,3,4,4,5,5,5-Undecafluoro-n-(2-Hydroxyethyl)Pentane-1-Sulphonamide is a specialized fluorinated sulphonamide derivative, engineered to deliver exceptional surface activity and chemical stability. This compound matters for its unique combination of a highly fluorinated hydrophobic tail and a hydrophilic hydroxyl group, making it a powerful surfactant and intermediate for demanding applications. It is primarily needed by manufacturers in the fluoropolymer processing, advanced coatings, and specialty chemical synthesis sectors where performance under extreme conditions is critical.

Application

• As a key surfactant and emulsifier in the polymerization of fluorinated monomers (e.g., PTFE, FKM).
• As a surface-modifying additive in high-performance coatings, paints, and inks to enhance leveling, wetting, and anti-foaming properties.
• As a critical chemical intermediate for synthesizing more complex fluorinated sulphonamides and sulfonyl compounds.
• In the formulation of fire-fighting foams (AFFF) and other specialty fluids requiring high thermal and chemical stability.
• For research and development of novel membrane materials and ion-exchange resins.
• As a processing aid in the manufacture of electronics and semiconductors where contamination control is paramount.

Quality Control

Our n-Ethyl-1,1,2,2,3,3,4,4,5,5,5-Undecafluoro-n-(2-Hydroxyethyl)Pentane-1-Sulphonamide is produced under a strict quality management system. Each batch undergoes rigorous analytical testing, including HPLC for purity, NMR for structural confirmation, and KF titration for moisture content, to ensure it meets precise specifications. Certificates of Analysis (COA) detailing all test results are provided with every shipment to guarantee traceability and batch-to-batch consistency for your critical processes.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). Keep away from strong alkalis and incompatible materials. Due to the chemical nature of fluorides, ensure containers are kept tightly sealed to prevent moisture absorption and contamination.
