Quality Control

Our production of (1Ar)-1Aβ,2,3,3A,4,5,6,7Bβ-Octahydro-1,1,3Aβ,7-Tetramethyl-1H-Cyclopropa[A]Naphthalene adheres to a rigorous quality management system. Every batch is analyzed using advanced chromatographic and spectroscopic techniques (GC, HPLC, NMR) to ensure identity, purity, and consistency. A comprehensive Certificate of Analysis (COA) detailing all specifications is provided with each shipment and is available upon request.

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 inert conditions for long-term stability.
