Quality Control

Our 1-Heptyl-3-Methylimidazolium Bis(Trifluoromethylsulfonyl)Imide is produced under stringent quality management protocols. Each batch undergoes rigorous analytical testing, including NMR, HPLC, and Karl Fischer titration, to ensure the specified purity of >99% and minimal levels of halide and water impurities. Certificates of Analysis (COA) documenting all test results are available upon request to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. This material is hygroscopic (moisture-sensitive) and should be stored under an inert atmosphere (e.g., nitrogen or argon) in a cool, dry place at room temperature (15-25°C). Minimize exposure to air and moisture during handling to maintain product integrity.
