Quality Control

Our 1,2-Cyclohexanediamine,1-Methyl-,(1R,2S)-Rel-(9Ci) is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including chiral purity determination by HPLC, to ensure it meets the exacting standards required for pharmaceutical and advanced synthetic applications. Certificates of Analysis (COA) with full traceability are provided for every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen) after opening to prevent moisture absorption and degradation.
