Quality Control

Our (1R,4E,8E)-6,6,9-Trimethyl-2-Methylene-4,8-Cycloundecadiene-1-Ol is produced under strict quality management systems. Each batch undergoes rigorous analytical testing, including chiral purity analysis by HPLC and GC, to ensure high chemical and isomeric purity. Certificates of Analysis (COA) detailing identity, purity, and impurity profiles are provided with every shipment to support your quality assurance and regulatory needs.

Storage

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