Quality Control

Our (4As,8Aα)-Decahydro-4A-Methyl-1-Methylene-8α-Isopropenylnaphthalene is produced and tested under strict quality management systems. Each batch undergoes rigorous analytical testing, including GC, GC-MS, and chiral analysis where applicable, to ensure high purity and consistent stereochemical integrity. 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 in a cool, dry, well-ventilated area at room temperature (15-25°C). This material is easily oxidized and should be stored under an inert atmosphere (e.g., nitrogen or argon) for long-term stability. Keep away from strong oxidizing agents.
