Quality Control

Our 1,2-Cyclohexanedicarbonyl Dichloride, (1R,2R)-Rel- (9Ci) is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including chiral purity assessment by HPLC, to ensure compliance with exacting standards for research and industrial use. A comprehensive Certificate of Analysis (COA) detailing identity, purity, enantiomeric excess, and impurity profiles is provided with 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). This material is hygroscopic (moisture-sensitive) and reacts with strong acids/organic solvents; keep the container tightly sealed under an inert atmosphere (e.g., nitrogen or argon) for long-term storage to prevent hydrolysis and maintain product integrity. Keep away from heat, open flames, and incompatible materials.
