Description

1-Ethylpyridinium Bis(Trifluoromethylsulfonyl)Imide is a high-purity ionic liquid belonging to the pyridinium cation family. This compound is valued for its excellent thermal stability, low volatility, and high ionic conductivity, making it a critical component in advanced electrochemical systems. It is primarily sought by researchers and manufacturers in the energy storage, chemical synthesis, and materials science sectors for applications requiring a stable, non-aqueous electrolyte medium.

Application

• As a high-performance electrolyte component in lithium-ion batteries, supercapacitors, and other advanced energy storage devices.
• As a green solvent or catalyst in organic synthesis and separation processes, offering an alternative to volatile organic compounds (VOCs).
• In electrochemical devices such as sensors, actuators, and dye-sensitized solar cells (DSSCs) due to its high ionic mobility.
• As a functional additive in polymer electrolytes and ion-conductive membranes for fuel cells.
• For research and development in materials science, particularly in studying ion transport mechanisms and phase behavior.
• In gas separation and capture technologies where selective solubility is required.

Quality Control

Our 1-Ethylpyridinium Bis(Trifluoromethylsulfonyl)Imide is manufactured under strict quality management protocols. Each batch undergoes rigorous analytical testing, including HPLC, NMR, and Karl Fischer titration, to ensure high purity and consistency. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with every shipment to support your quality assurance and R&D documentation needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and should be handled under a dry inert atmosphere to prevent degradation. Keep away from strong bases and incompatible materials.
