Quality Control

Our 3,3'-Dichlorobenzidine Dihydrochloride is produced under stringent quality management protocols. Each batch undergoes comprehensive analytical testing to ensure it meets precise specifications for identity, purity, and impurity profiles. A Certificate of Analysis (COA) detailing the results is provided with every shipment to guarantee traceability and compliance with your quality requirements.

Storage

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