Quality Control

Our 1,2-Cycloheptanediamine,(1R,2R)-(9Ci) is produced under strict quality management systems. Each batch undergoes comprehensive analytical testing, including chiral purity verification by HPLC, to ensure it meets the high standards required for research and development. A Certificate of Analysis (COA) detailing identity, purity, and specific test results is 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 nature, the container must be kept tightly sealed to prevent moisture absorption, which can affect product stability and performance. For long-term storage, consider using an inert atmosphere.
