Quality Control

Our (1R,2R)-(-)-1,2-Diaminocyhexane is produced under strict quality management systems. Each batch undergoes comprehensive analytical testing, including chiral purity assessment by HPLC, to ensure it meets the high standards required for sensitive asymmetric synthesis. Certificates of Analysis (COA) detailing identity, purity, and enantiomeric excess are provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) in a cool, dry place. Due to its hygroscopic and easily oxidized nature, the container should be flushed with inert gas after each opening. Recommended storage temperature is 2-8°C for long-term stability.
