It is primarily utilized in advanced material science, electronics, and specialty coatings where superior performance under demanding conditions is required. The compound is identified by CAS number 93894-70-3.

Application

• Electrolyte Additive for Lithium-Ion Batteries: Enhances high-voltage stability and cycle life by forming a stable solid-electrolyte interphase (SEI) layer.
• Hydrophobic Coating Agent: Imparts exceptional water and oil repellency to textiles, paper, and electronic components.
• Phase-Transfer Catalyst (PTC): Facilitates reactions between reagents in immiscible phases, particularly in fluorination and organic synthesis.
• Surfactant for Fluorinated Systems: Used as a stabilizer and emulsifier in the production of fluoropolymers like PTFE and specialty fluorinated coatings.
• Antistatic Agent: Provides surface conductivity and reduces static charge buildup in photographic films and electronic packaging.
• Ionic Liquid Solvent: Serves as a green, non-volatile reaction medium for catalysis and electrochemical applications.

Quality Control

Our Tetraethylammonium Heptadecafluoroisooctanesulphonate is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity, Karl Fischer titration for moisture content, and NMR/IR for structural confirmation, to ensure it meets precise customer specifications. A comprehensive Certificate of Analysis (COA) detailing all test results is provided with every shipment.

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) and must be kept under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation from atmospheric moisture.
