Quality Control

Our 1-Methyl-3-(3-Sulfopropyl)-1H-Imidazol-3-Ium is manufactured under a strict quality management system. Every batch undergoes rigorous analytical testing, including HPLC for purity and NMR for structural confirmation, to ensure it meets exacting specifications. Certificates of Analysis (COA) documenting identity, purity, and impurity profiles are provided with each shipment. We support compliance with REACH and other global regulatory frameworks.

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). This product is hygroscopic (moisture-sensitive). Keep the container tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent moisture absorption and degradation.
