Quality Control

Our 1,3-Dimethylimidazolium Trifluoromethanesulfonate is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including NMR, HPLC, and Karl Fischer titration, to ensure it meets the high-purity standards required for research and industrial applications. A detailed Certificate of Analysis (COA) is provided with every shipment, confirming identity, purity, and key physical parameters.

Storage

Preserve in a tightly closed container, protected from light. This material is hygroscopic (moisture-sensitive) and must be stored in a cool, dry place under an inert atmosphere (e.g., nitrogen or argon) for long-term stability. Recommended storage temperature is 2-8°C. Allow the container to reach room temperature before opening to minimize moisture ingress.
