Quality Control

Our Ethanone, 1-(6-Methyl-3-Cyclohexen-1-Yl)-, (1R-Trans)- (9Ci) is produced under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including chiral purity analysis by GC or HPLC, to ensure consistent enantiomeric excess and chemical identity. Certificates of Analysis (COA) detailing specific results for purity, optical rotation, and impurity profiles are provided and available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, 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 stability and to minimize degradation. Keep away from heat, sparks, and open flames.
