Quality Control

Our 1-Butyl-1-Methylpyrrolidinium Bis(Trifluoromethylsulfonyl)Imide is manufactured under strict quality management systems. Every batch undergoes rigorous analytical testing, including NMR, HPLC, and Karl Fischer titration, to ensure high purity and consistency essential for electrochemical applications. Certificates of Analysis (COA) with detailed specifications are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). Due to its hygroscopic nature, containers should be kept tightly sealed under an inert atmosphere (e.g., argon or nitrogen) to prevent moisture absorption. Keep away from strong oxidizing agents.
