Quality Control

Our 1-Carboxyethyl-3-Methylimidazolium Hydrogensulfate is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing, including HPLC for purity and NMR for structural confirmation, to ensure it meets precise specifications for research and industrial use. Certificates of Analysis (COA) documenting all critical parameters are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after use to prevent absorption of atmospheric moisture, which may affect product performance.
