Quality Control

Our [1S,(-)]-1,2,3,4,4Aα,5,6,8Aα-Octahydro-7-Methyl-4-Methylene-1-Isopropylnaphthalene is produced under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including chiral purity verification by GC or HPLC, to ensure it meets the high standards required for research and industrial synthesis. A detailed Certificate of Analysis (COA) is provided with every shipment, confirming identity, purity, and other critical parameters.

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 controlled room temperature (15-25°C). Due to its sensitivity to oxidation, the container should be kept sealed after initial use to minimize exposure to air.
