Quality Control

Our (E)-Ethene-1,2-Diamine Dihydrochloride is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation, to ensure it meets exacting standards for research and industrial use. Certificates of Analysis (COA) with full traceability are provided with every shipment.

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 tightly sealed after opening to prevent degradation from atmospheric moisture.
