Description

3-[(Carboxymethyl)[(Heptadecafluorooctyl)Sulphonyl]Amino]Propyltrimethylammonium Hydroxide is a highly specialized fluorinated surfactant and quaternary ammonium compound. This unique structure combines the exceptional surface activity and chemical resistance of perfluorinated chains with the cationic charge of a quaternary ammonium group, making it a powerful tool for modifying surface properties. It is primarily utilized in advanced material science and high-performance coating formulations where standard surfactants fail. Industries requiring extreme chemical stability, low surface energy, or specific ionic interactions will find this compound critical for their development and production processes.

Application

• As a key fluorinated cationic surfactant in fire-fighting foams (AFFF) for hydrocarbon and polar solvent fires.
• As a surface modifier and leveling agent in high-performance fluoropolymer coatings and paints to enhance wetting and film formation.
• As an additive in electronic materials, such as photoresists and anti-reflective coatings, for semiconductor manufacturing.
• In the formulation of oil and water repellents for textiles, leather, and paper.
• As a compatibilizer and emulsifying agent for fluorinated monomers in polymerization processes.
• In specialty cleaning and etching solutions for the electronics and aerospace industries.
• For research and development of novel biomedical materials and drug delivery systems requiring fluorinated surfaces.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This material is a strong alkali and should be kept separate from acids and reactive materials. Due to its ionic and fluorinated nature, prolonged exposure to high humidity should be avoided to prevent potential hydrolysis or caking.
