Description

1,1,2,2-Tetrafluoro-2-(1,1,2,2,3,3,4,4-Octafluoro-4-Sulfinobutoxy)-Ethanesulfonic Acid Disodium Salt is a high-purity, fluorinated sulfonic acid derivative with unique surfactant and electrolyte properties. This compound is valued for its exceptional chemical and thermal stability, derived from its perfluorinated backbone, making it suitable for demanding industrial environments. It is primarily sought by manufacturers in the specialty chemical, advanced materials, and electronics sectors for applications requiring high-performance fluorosurfactants or ion-exchange materials.

Application

• Fluorosurfactant and Leveling Agent: Used in high-performance coatings, paints, and fire-fighting foams to reduce surface tension and improve wetting and spreading.
• Electrolyte Additive: Employed in advanced battery systems, such as lithium-ion batteries, to enhance electrolyte stability and electrode performance.
• Catalyst and Reaction Intermediate: Serves as a building block or catalyst in organic synthesis, particularly for introducing fluorinated sulfonate groups.
• Ion-Exchange Membrane Precursor: A key monomer or additive in the production of perfluorinated ion-exchange membranes used in chlor-alkali processes and fuel cells.
• Specialty Polymer Modification: Incorporated into polymers to impart oil, water, and stain repellency, as well as chemical resistance.
• Electroplating and Metal Finishing: Acts as a wetting agent and conductivity enhancer in electroplating baths for improved deposit quality.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed after each use to prevent moisture absorption, which can affect product quality and performance. Keep away from incompatible materials.
