Description

Poly(Difluoromethylene), α-Fluoro-ω-[2- [[2-(Trimethylammonio)Ethyl]Thio]Ethyl]-, Methyl Sulfate is a specialized fluorinated quaternary ammonium compound with a unique cationic surfactant structure. This chemical is engineered to deliver exceptional surface activity and stability in demanding formulations, making it a critical performance additive. It is primarily utilized in advanced material science and high-performance industrial applications where its fluorinated chain imparts specific properties like oil and water repellency, while the cationic moiety provides substantivity to surfaces.

Application

• Specialty Surfactant & Emulsifier: Acts as a high-performance cationic fluorosurfactant for creating stable emulsions and microemulsions in aggressive solvent systems.
• Textile & Fiber Treatment: Used as a key ingredient in durable water and oil repellent (DWR) finishes for technical textiles and high-end apparel.
• Paper & Packaging Coatings: Imparts grease resistance and barrier properties to specialty papers and food packaging materials.
• Electronics & Semiconductor Processing: Employed as a surfactant in photoresist developers and cleaning formulations for wafer processing.
• Firefighting Foams (AFFF): Serves as a fluorosurfactant component in some film-forming fluoroprotein (FFFP) and aqueous film-forming foam (AFFF) concentrates.
• Personal Care & Cosmetics: Used in specialized hair conditioning products and skin care formulations requiring unique substantivity and feel.
• Lithium-Ion Battery Electrolytes: Investigated as a functional additive to improve electrolyte stability and electrode interface performance.
• Biomedical Research: Applied in cell membrane studies and as a component in non-viral gene delivery vectors due to its cationic nature.

Quality Control

Every batch of our fluorinated quaternary ammonium surfactant is produced under strict quality management systems to ensure consistency and performance. We employ advanced analytical techniques including NMR, HPLC, and titration methods to verify chemical identity, assay/purity, and critical impurity profiles. A comprehensive Certificate of Analysis (COA) detailing batch-specific results is provided with each shipment to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at a controlled room temperature (15-25°C). Keep away from strong bases and incompatible materials. This material is hygroscopic (moisture-sensitive); ensure containers are sealed tightly after use to prevent moisture uptake.
