Quality Control

Our 1,1'-Biadamantane-3-3'-Diamine Dihydrochloride is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity, NMR and IR for structural confirmation, and Karl Fischer titration for moisture content, to ensure it meets the high standards required for research and development. A detailed Certificate of Analysis (COA) is provided with every shipment, guaranteeing traceability and compliance with your specifications.

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 nature, the container must be kept tightly sealed after each use to prevent moisture absorption, which can affect purity and stability. For long-term storage, consider using a desiccator or inert atmosphere.
