Quality Control

Our [R,(+)]-2,3,4,4A,5,6-Hexahydro-1,4A-Dimethyl-7-(1-Methylethyl)Naphthalene is manufactured under strict quality management systems. Each batch is subjected to comprehensive analytical testing, including chiral purity analysis by GC or HPLC, to ensure it meets the high standards required for research and synthesis. Certificates of Analysis (COA) detailing identity, purity, and chiral excess are provided with every shipment.

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 room temperature (15-25°C). Due to its sensitivity to oxidation, minimize headspace in opened containers and handle under an inert atmosphere for long-term stability.
