Quality Control

Our 1,2-Cyclohexanediamine,3-Methyl-,(1R,2S,3S)-(9Ci) is produced under strict quality management systems. Each batch undergoes rigorous analytical testing, including chiral purity verification by HPLC, to ensure compliance with exacting standards for research and 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 in a cool, dry, well-ventilated place at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation.
