Quality Control

Every batch of our ionic liquids undergoes rigorous quality testing to ensure compliance with stringent purity and consistency standards. Our analytical protocols include NMR, HPLC, and Karl Fischer titration to verify chemical identity, assay purity, and moisture content. A comprehensive Certificate of Analysis (COA) detailing all specifications and test results is provided with each shipment and is available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). This product is hygroscopic (moisture-sensitive). To prevent degradation and maintain purity, containers should be kept sealed under an inert atmosphere (e.g., nitrogen or argon) when not in use and opened only in a dry, controlled environment.
