Description

2,3,3,3-Tetrafluoro-2-[1,1,2,2-Tetrafluoro-2-(Fluorosulphonyl)Ethoxy]Propionyl Fluoride is a high-value fluorinated building block and intermediate. This compound matters for its unique perfluorinated ether and sulfonyl fluoride functionalities, which are critical for introducing specific properties into advanced materials. It is primarily needed by R&D chemists and process engineers in the pharmaceutical, agrochemical, and specialty polymer industries for synthesizing novel active ingredients and high-performance fluoropolymers.

Application

• Pharmaceutical Intermediate: Used in the synthesis of novel drug candidates, particularly those requiring fluorinated motifs to enhance metabolic stability, bioavailability, and membrane permeability.
• Agrochemical Synthesis: Serves as a key fluorinating agent and building block for creating advanced herbicides, pesticides, and fungicides with improved efficacy and environmental profiles.
• Fluoropolymer Production: Acts as a monomer or modifier in the production of specialty fluorinated polymers and coatings, imparting exceptional chemical resistance, thermal stability, and low surface energy.
• Lithium-Ion Battery Electrolytes: Investigated as a precursor for novel fluorinated electrolyte additives or solvents that can improve battery safety, performance, and cycle life.
• Surface Modification Agent: Utilized to create permanent, low-energy fluorinated surfaces on materials for anti-fouling, anti-icing, or hydrophobic applications.
• Organic Synthesis Reagent: Employed in research laboratories as a versatile reagent for introducing fluorosulfonyl and perfluoroether groups into complex organic molecules.

Quality Control

Every batch of 2,3,3,3-Tetrafluoro-2-[1,1,2,2-Tetrafluoro-2-(Fluorosulphonyl)Ethoxy]Propionyl Fluoride is produced and tested under strict quality management systems. We ensure compliance with relevant industry standards for high-purity fluorochemical intermediates. Comprehensive analytical testing, including NMR (19F, 1H), FT-IR, and GC/HPLC, is performed to verify identity, purity, and impurity profiles. A detailed Certificate of Analysis (COA) is provided with each shipment to guarantee specification adherence and batch-to-batch consistency for your critical processes.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) and highly volatile nature, containers must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation and moisture uptake. Keep away from strong acids, bases, and oxidizing agents.
