Description

2-[(8-Chloro-1,1,2,2,3,3,4,4,5,5,6,6,7,7,8,8-Hexadecafluorooctyl)Oxy]-1,1,2,2-Tetrafluoroethanesulfonyl Fluoride is a highly fluorinated sulfonyl fluoride derivative, serving as a critical building block for introducing perfluoroalkyl ether sulfonyl functionalities. Its value lies in its unique combination of extreme hydrophobicity, oleophobicity, and chemical resistance derived from its perfluorinated chain and reactive sulfonyl fluoride group. This compound is essential for researchers and manufacturers in advanced material science, particularly for developing high-performance surface modifiers, specialty polymers, and novel surfactants with tailored properties.

Application

• Key Intermediate for Fluorinated Surfactants & Polymers: Acts as a reactive monomer or precursor for synthesizing perfluoroalkyl ether-based surfactants and polymers with exceptional surface activity and stability.
• Surface Modification Agent: Used to impart permanent oil-, water-, and stain-repellent characteristics to textiles, papers, and membranes.
• Lithography and Semiconductor Processing: Potential application in the formulation of advanced photoresists and anti-reflective coatings for next-generation semiconductor manufacturing.
• Pharmaceutical & AgroChemical Intermediates: Serves as a specialized fluorinating agent or building block for creating bioactive molecules with improved metabolic stability and membrane permeability.
• Fuel Cell & Battery Component Research: Investigated for use in proton exchange membranes (PEMs) and electrolyte materials due to its potential for high ionic conductivity and chemical inertness.
• Specialty Coatings and Adhesives: Incorporated into formulations requiring extreme chemical resistance, low surface energy, and durability in harsh environments.

Quality Control

Every batch of our 2-[(8-Chloro-1,1,2,2,3,3,4,4,5,5,6,6,7,7,8,8-Hexadecafluorooctyl)Oxy]-1,1,2,2-Tetrafluoroethanesulfonyl Fluoride undergoes rigorous analytical testing to ensure high purity and consistent performance. Our quality assurance protocols are designed to meet the stringent requirements of research and industrial-scale synthesis. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with each shipment to guarantee traceability and compliance with your specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place. Due to its hygroscopic and strong acid/organic solvent nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) to prevent moisture absorption and decomposition. Recommended long-term storage temperature is 2-8°C.
