Description

1,1,2,2-Tetrafluoro-2-(1,1,2,2,3,3,4,4-Octafluoro-4-Iodobutoxy)Ethanesulfonyl Fluoride is a highly fluorinated, iodinated ether sulfonyl fluoride derivative, serving as a critical building block for advanced material synthesis. This compound is valued for its unique combination of a reactive sulfonyl fluoride group and a perfluoroalkyl iodide segment, enabling precise functionalization and polymerization. It is primarily sought by R&D chemists and process engineers in the pharmaceutical, agrochemical, and specialty polymer industries for creating novel fluorinated compounds with enhanced properties.

Application

• Pharmaceutical Intermediate: Used in the synthesis of active pharmaceutical ingredients (APIs), particularly for introducing fluorinated motifs to improve metabolic stability and bioavailability.
• Agrochemical Synthesis: Serves as a key precursor for developing novel fluorinated pesticides and herbicides with increased efficacy and environmental persistence.
• Polymer & Material Science: Acts as a monomer or cross-linking agent for producing high-performance fluoropolymers with exceptional chemical resistance, low surface energy, and thermal stability.
• Surface Modification: Employed to create self-assembled monolayers (SAMs) or to fluorinate surfaces, imparting oil- and water-repellent characteristics.
• Liquid Crystal & Electronic Materials: Utilized in the development of fluorinated liquid crystals and dielectric materials for advanced display and semiconductor applications.
• Click Chemistry & Bioconjugation: The sulfonyl fluoride group allows for selective, rapid reactions under mild conditions, useful in probe labeling and bioconjugation strategies.

Quality Control

Our production of 1,1,2,2-Tetrafluoro-2-(1,1,2,2,3,3,4,4-Octafluoro-4-Iodobutoxy)Ethanesulfonyl Fluoride adheres to stringent quality protocols to ensure batch-to-batch consistency and high purity for research and scale-up applications. Each lot is analyzed using advanced techniques including NMR (¹⁹F, ¹H), HPLC, and FT-IR to confirm identity and purity. A comprehensive Certificate of Analysis (COA) detailing all specifications is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from incompatible materials such as strong bases and reducing agents. Due to its sensitivity to strong acid/organic solvent conditions and potential light sensitivity, it is recommended to store under an inert atmosphere (e.g., nitrogen or argon) at temperatures between 2°C and 8°C for long-term stability. Allow the container to reach room temperature before opening to prevent moisture condensation.
