Description

2,2'-Oxybis(1,1,2,2-Tetrafluoro)-Ethanesulfonyl Chloride is a high-value fluorinated sulfonyl chloride building block, essential for introducing perfluoroether sulfonyl functionalities into target molecules. Its core value lies in enabling the synthesis of advanced materials with exceptional chemical and thermal stability, as well as unique surface properties. This compound is critically needed by R&D chemists and process engineers in the pharmaceutical, agrochemical, and specialty polymer industries for developing novel active ingredients and high-performance materials.

Application

• Pharmaceutical Intermediate: Key building block for synthesizing novel active pharmaceutical ingredients (APIs), particularly those requiring enhanced metabolic stability and membrane permeability.
• Agrochemical Synthesis: Used in the development of next-generation herbicides, fungicides, and insecticides where the perfluoroether moiety imparts weather resistance and biological activity.
• Polymer & Material Science: Serves as a monomer or cross-linking agent for creating specialty fluoropolymers, surfactants, and coatings with outstanding oil, water, and chemical repellency.
• Lithium-Ion Battery Electrolytes: Potential component in the synthesis of novel sulfonylimide-based lithium salts for high-voltage, high-stability electrolytes.
• Liquid Crystal & OLED Materials: Intermediate for producing fluorinated components used in electronic display technologies to improve performance and longevity.
• Surface Modification Reagent: Used to functionalize surfaces (e.g., silicon, glass, polymers) to create low-energy, non-stick, or highly specific reactive interfaces.
