Quality Control

Our Ethyl(3-Methoxypropyl)Dimethylammonium Bis(Trifluoromethanesulfonyl)Imide is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including NMR, HPLC, and ion chromatography, to ensure high purity and consistency for demanding electrochemical applications. A comprehensive Certificate of Analysis (COA) detailing purity, water content, and halide impurities is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Due to its hygroscopic (moisture-sensitive) nature, store under a dry, inert atmosphere (e.g., nitrogen or argon) at a controlled room temperature (15-25°C). Keep away from strong bases and incompatible materials.
