Quality Control

Our (1S)-1,2,3,4,4Aβ,5,6,8Aβ-Octahydro-7-Methyl-4-Methylene-1α-Isopropylnaphthalene is manufactured under strict quality management systems. Every batch undergoes rigorous analytical testing, including chiral purity verification by GC or HPLC, to ensure it meets the high standards required for research and synthesis. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with each shipment to guarantee traceability and consistency for your critical applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at 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 preservation. Keep away from heat, sparks, and open flames.
