Quality Control

Our (1R)-1,2,4Aβ,5,6,8Aα-Hexahydro-4,7-Dimethyl-1β-Isopropylnaphthalene is produced under strict quality management protocols. Each batch undergoes rigorous analytical testing, including chiral purity assessment, to ensure compliance with exacting research and development standards. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with every shipment to guarantee traceability and support your regulatory documentation needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at controlled room temperature (15-25°C). This material is easily oxidized and should be handled under an inert atmosphere (e.g., nitrogen or argon) for long-term storage or when opening containers to maintain purity and prevent degradation.
