Description

n-Hexyl-4-Methylpyridinium Bis((Trifluoromethyl)Sulfonyl)Imide is a high-purity ionic liquid belonging to the pyridinium-based cation family paired with the hydrophobic bis(trifluoromethanesulfonyl)imide anion. This compound is valued for its unique combination of high thermal stability, low viscosity, and excellent electrochemical window, making it a superior solvent and electrolyte component. It is primarily sought by researchers and manufacturers in the fields of advanced battery technology, electrodeposition, and catalysis where non-aqueous, conductive media are required.

Application

• Electrolyte Component for Lithium-Ion and Next-Generation Batteries: Used as a co-solvent or additive to enhance ionic conductivity, thermal stability, and safety in high-voltage battery systems.
• Green Solvent for Catalysis: Serves as a non-volatile, recyclable reaction medium for various organic transformations, including cross-coupling and polymerization reactions.
• Electroplating and Electrodeposition: Employed in the electrodeposition of metals and semiconductors where aqueous solutions are unsuitable, enabling the deposition of reactive metals like aluminum and magnesium.
• Gas Separation and Capture: Utilized in supported ionic liquid membranes (SILMs) for the selective absorption and separation of gases such as CO2 and SO2.
• Lubricant and Additive: Functions as a high-performance lubricant or anti-wear additive for demanding mechanical applications due to its low vapor pressure and thermal stability.
• Analytical Chemistry: Acts as a stationary phase modifier in chromatography or a matrix in mass spectrometry for analyzing complex mixtures.

Quality Control

Our production of n-Hexyl-4-Methylpyridinium Bis((Trifluoromethyl)Sulfonyl)Imide adheres to stringent quality protocols to ensure batch-to-batch consistency and high purity. Each lot is characterized using advanced analytical techniques including NMR, HPLC, and Karl Fischer titration to verify identity, purity, and moisture content. Certificates of Analysis (COA) documenting all critical specifications are provided with every shipment and are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Due to its hygroscopic (moisture-sensitive) nature, store under an inert atmosphere (e.g., nitrogen or argon) in a cool, dry place. Recommended long-term storage temperature is 2-8°C. Allow the container to reach room temperature before opening to minimize moisture ingress. Keep away from strong oxidizing agents.
