Description

2-[(6-Chloro-1,1,2,2,3,3,4,4,5,5,6,6-Dodecafluorohexyl)Oxyl]-1,1,2,2-Tetrafluoroethanesulfonic Acid,Potassium Salt is a highly fluorinated sulfonate salt, a member of the perfluoroalkyl ether sulfonate (PFESA) chemical family. This compound is valued for its exceptional chemical and thermal stability, derived from its perfluorinated backbone, making it a critical intermediate and functional additive in advanced material science. It is primarily sought by R&D and production teams in the pharmaceutical, agrochemical, and specialty polymer industries for applications requiring inert, high-performance fluorochemical building blocks.

Application

• Pharmaceutical Intermediate: Used in the synthesis of novel active pharmaceutical ingredients (APIs), particularly where fluorination is required to modulate bioavailability, metabolic stability, or lipophilicity.
• Agrochemical Synthesis: Serves as a key fluorinated building block for creating advanced herbicides, fungicides, and insecticides with enhanced environmental persistence and efficacy.
• Polymer & Material Science: Acts as a monomer or additive for producing high-performance fluoropolymers and surface coatings with superior oil, water, and chemical resistance.
• Lithium-Ion Battery Electrolytes: Investigated as a potential electrolyte additive or lithium salt component to improve thermal stability and cycle life of high-voltage battery systems.
• Surfactant & Surface Modification: Functions as a precursor for specialty fluorosurfactants used in demanding industrial applications like fire-fighting foams and etching solutions.
• Catalysis & Ligand Synthesis: Employed in the development of novel catalysts and ligands for organic synthesis, leveraging the electron-withdrawing nature of the perfluoroether sulfonate group.

Quality Control

Our production of this specialty fluorochemical adheres to a strict quality management system. Each batch is characterized using advanced analytical techniques including NMR, HPLC, and ICP-MS to ensure identity, purity, and consistency. A comprehensive Certificate of Analysis (COA) is provided with every shipment, detailing key parameters such as assay, impurity profile, moisture content, and heavy metal limits. We support compliance with REACH and other global regulatory frameworks upon request.

Storage

Preserve in a tightly closed container, protected from light. This material is hygroscopic (moisture-sensitive). Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Keep the container tightly sealed under an inert atmosphere (e.g., nitrogen or argon) to prevent moisture absorption and potential degradation. Store away from incompatible materials.
