Description

Tetrafluoro-2-(Pentafluoroethoxy)Ethanesulfonic Acid Sodium Salt is a high-value, specialty fluorinated sulfonate salt with unique chemical properties derived from its perfluoroether and sulfonic acid structure. This compound matters for its role as a key intermediate or additive in advanced chemical synthesis, particularly where high thermal stability, chemical resistance, and specific ionic characteristics are required. It is primarily needed by R&D chemists and process engineers in the pharmaceutical, agrochemical, and advanced materials sectors for developing novel compounds and functional materials.

Application

• Pharmaceutical Intermediate: Used in the synthesis of novel active pharmaceutical ingredients (APIs), especially those requiring fluorinated motifs for enhanced metabolic stability and bioavailability.
• Agrochemical Synthesis: Serves as a building block for advanced herbicides, fungicides, and pesticides where the introduction of fluorine atoms improves efficacy and environmental persistence.
• Polymer & Material Science: Acts as a monomer or additive for producing specialty fluoropolymers, surfactants, and ion-exchange membranes with exceptional chemical and thermal resistance.
• Electrolyte Additive: Investigated for use in advanced battery systems, such as lithium-ion batteries, to improve electrolyte stability and electrode performance.
• Catalysis & Ligand Synthesis: Employed in the development of novel catalysts and ligands for organic synthesis, leveraging the electron-withdrawing nature of the perfluoroalkoxy sulfonate group.
• Surface Modification Agent: Used to impart hydrophobic and oleophobic properties to surfaces in coatings and textile treatments.

Quality Control

Our Tetrafluoro-2-(Pentafluoroethoxy)Ethanesulfonic Acid Sodium Salt is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing to ensure identity, purity, and consistency. We provide comprehensive Certificates of Analysis (COA) detailing key parameters such as assay, impurity profile, and moisture content. Our quality commitment supports applications requiring high-purity intermediates for research and commercial scale-up.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent degradation from atmospheric moisture. Keep away from incompatible materials such as strong acids and strong bases.
