Quality Control

Our 2-Cyclohexen-1-One, 3-Methyl-5-(1-Methylethenyl)-, (5R)- (9Ci) is produced under strict quality management systems. Each batch undergoes rigorous analytical testing, including chiral purity analysis, to ensure it meets the high standards required for research and industrial synthesis. Certificates of Analysis (COA) detailing identity, purity, enantiomeric excess, and impurity profiles are provided with every shipment to guarantee traceability and compliance with your specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at controlled room temperature (15-25°C). Due to its highly volatile and easily oxidized nature, it is recommended to store under an inert atmosphere (e.g., nitrogen or argon) for long-term preservation and to minimize degradation. Keep away from heat, sparks, and open flame.
