Description

1-Methylpyridinium Bis(Trifluoromethanesulfonyl)Imide is a high-purity ionic liquid salt, also known as [MPy][TFSI]. This compound is valued for its excellent thermal stability, wide electrochemical window, and high ionic conductivity, making it a critical component in advanced energy storage and material science applications. It is primarily sought by researchers and manufacturers in the fields of electrolytes for lithium-ion batteries, supercapacitors, and electrodeposition, as well as in catalysis and chemical synthesis where a stable, non-aqueous ionic medium is required.

Application

• Electrolyte Additive/Solvent for Lithium-ion Batteries: Enhances ionic conductivity, thermal stability, and safety of high-performance battery systems.
• Electrolyte for Supercapacitors (EDLCs): Used in formulations to achieve high voltage windows and improved energy density.
• Medium for Electrodeposition: Enables the electroplating of reactive metals like aluminum and magnesium from non-aqueous solutions.
• Green Solvent for Catalysis: Serves as a recyclable, non-volatile solvent for various organic synthesis and catalytic reactions.
• Component in Polymer Electrolytes: Incorporated into solid or gel polymer matrices to create flexible, conductive membranes for solid-state devices.
• Gas Separation Membranes: Utilized in supported ionic liquid membranes (SILMs) for selective CO2 capture and separation processes.
• Analytical Chemistry: Employed as a stationary phase modifier in chromatography or as a matrix in mass spectrometry.

Quality Control

Our 1-Methylpyridinium Bis(Trifluoromethanesulfonyl)Imide is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity, Karl Fischer titration for water content, and ICP-MS for trace metal analysis, to ensure it meets the stringent requirements for electrochemical and synthetic applications. Certificates of Analysis (COA) with full traceability are provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This product is hygroscopic (moisture-sensitive). Keep the container tightly sealed under an inert atmosphere (e.g., nitrogen or argon) to prevent moisture absorption and degradation.
