Quality Control

Our 1-Ethyl-2-Methyl-1H-Imidazole-4-Sulfonyl Chloride is manufactured under strict quality management systems. Every batch undergoes rigorous analytical testing, including HPLC, NMR, and IR spectroscopy, to ensure high purity and consistency. We provide comprehensive Certificates of Analysis (COA) with each shipment, detailing all specification parameters. Our quality commitment supports compliance with cGMP and ICH guidelines for advanced intermediates.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled 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., nitrogen or argon) after opening to prevent degradation. Keep away from heat, open flames, and incompatible materials such as strong bases, alcohols, and amines.
