Quality Control

Our 1-Methyl-4-[(R)-1-Methyl-5-Hexenyl]-1,3-Cyclohexadiene is produced under strict quality management systems. Each batch undergoes rigorous analytical testing, including chiral purity analysis by GC or HPLC, to ensure high chemical and isomeric purity and batch-to-batch consistency. Certificates of Analysis (COA) detailing identity, purity, and impurity profiles are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) in a cool, well-ventilated place. Due to its highly volatile and easily oxidized nature, the recommended storage temperature is 2-8°C for long-term stability. Keep away from heat, sparks, open flames, and oxidizing agents.
