Quality Control

Our (1S,8Aβ)-Decahydro-1,4Aα-Dimethyl-6-Methylene-5α-[(E)-3-Methylpenta-2,4-Dienyl]-1-Naphthalenemethanol 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, and impurity profiles are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its sensitivity to oxidation, the container headspace should be minimized after opening.
