Quality Control

Our production of Ethyl(2-Methoxyethyl)Dimethylammonium Bis(Fluorosulfonyl)Imide adheres to stringent quality management protocols. Each batch is analyzed to ensure high purity and consistency, with key parameters including assay, anion/cation content, moisture (KF), and metal impurities controlled to meet exacting standards for electrolyte applications. A comprehensive Certificate of Analysis (COA) is provided with every shipment, detailing all test results.

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). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed under an inert atmosphere (e.g., argon or nitrogen) after opening to prevent moisture absorption and degradation.
