Quality Control

Our 6,6'-(Carbonyldiimino)Bis[1-Methylquinolinium] Sulphate is produced under strict quality management protocols. Each batch undergoes rigorous analytical testing to ensure identity, purity, and consistency. Certificates of Analysis (COA) documenting key parameters are available upon request, supporting compliance with research and industrial application standards.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent degradation from atmospheric moisture.
