Description

(Carboxymethyl)Dimethyl-3-[Methyl[(3,3,4,4,5,5,6,6,7,7,8,8,8-Tridecafluorooctyl)Sulphonyl]Amino]Propylammonium Hydroxide is a highly specialized fluorinated surfactant and phase-transfer catalyst. This compound is engineered to deliver exceptional surface activity and stability in demanding environments, particularly where both fluorine chemistry and strong alkaline conditions are required. It is a critical performance additive for industries seeking to enhance wetting, emulsification, and chemical resistance in advanced formulations. Key users include manufacturers in electronics, specialty polymers, and high-performance coatings.

Application

• Electronics Manufacturing: As a surfactant and leveling agent in photoresist strippers and cleaning formulations for semiconductor wafers.
• Fluoropolymer Processing: Acts as an emulsifier and stabilizer in the polymerization of fluorinated monomers (e.g., PTFE, FKM).
• Specialty Coatings & Inks: Provides superior wetting and flow control in fluorinated, chemical-resistant coatings and inks.
• Phase-Transfer Catalysis (PTC): Facilitates reactions between reagents in immiscible phases, particularly useful in organic synthesis under alkaline conditions.
• Fire-Fighting Foams (Legacy/Formulation R&D): Used in research and development of fluorosurfactant components for high-performance aqueous film-forming foams (AFFF).
• Textile & Leather Treatment: Imparts oil, water, and stain repellency to fabrics and leather goods.

Quality Control

Every batch of our (Carboxymethyl)Dimethyl-3-[Methyl[(3,3,4,4,5,5,6,6,7,7,8,8,8-Tridecafluorooctyl)Sulphonyl]Amino]Propylammonium Hydroxide is produced and tested under a strict quality management system. We ensure compliance with relevant industry standards and customer-specific requirements. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with each shipment to guarantee batch-to-batch consistency and performance reliability.

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 hygroscopic (moisture-sensitive) and contains a strong alkali; ensure containers are kept tightly sealed to prevent absorption of atmospheric moisture and carbon dioxide. Keep away from incompatible materials such as strong acids.
