Description

Sodium 1,1,2,2-Tetrafluoro-4-Hydroxybutane-1-Sulfonate is a high-value, organofluorine sulfonate salt with unique surfactant and electrolyte properties derived from its hybrid perfluoroalkyl and hydrophilic sulfonate structure. This compound is critical for applications requiring exceptional chemical stability, surface activity, and ionic conductivity in demanding environments. It is primarily sought by R&D and production teams in the advanced materials, specialty chemical, and electronics industries for formulating next-generation products.

Application

• Lithium-Ion Battery Electrolytes: As a functional additive or co-solvent to enhance electrolyte stability, improve SEI film formation, and increase battery cycle life at high voltages.
• Fluorinated Surfactants & Coatings: Serves as a key intermediate or monomer for synthesizing specialty fluorosurfactants, providing superior wetting, leveling, and anti-fog properties in high-performance coatings and films.
• Chemical Synthesis Intermediate: Used in organic synthesis, particularly in nucleophilic substitution and coupling reactions, to introduce a sulfonate-functionalized perfluoroalkyl chain into target molecules.
• Electroplating & Metal Finishing: Acts as a wetting agent and conductivity salt in specialized electroplating baths for improved metal deposition uniformity and surface quality.
• Specialty Polymer Modification: Incorporated as a comonomer or end-group to impart hydrophilicity, ionic character, and enhanced durability to fluoropolymers and other advanced polymers.

Quality Control

Our Sodium 1,1,2,2-Tetrafluoro-4-Hydroxybutane-1-Sulfonate is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure high purity, consistent composition, and reliable performance. Certificates of Analysis (COA) detailing purity, identity, and impurity profiles are provided with every shipment to support your quality assurance protocols.

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). This material is hygroscopic (moisture-sensitive); the container must be kept tightly sealed to prevent absorption of atmospheric moisture, which can affect product quality and performance.
