Quality Control

Our 4,5-Dimethyl-1,3-Bis-(2,4,6-Trimethylphenyl)-3H-Imidazol-1-Ium Chloride is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and NMR for structural confirmation, to ensure it meets exacting standards for research and industrial use. Certificates of Analysis (COA) with full traceability are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept sealed under an inert atmosphere (e.g., nitrogen or argon) for long-term storage to prevent degradation.
