Quality Control

Every batch of [2R,4Aβ]-Decahydro-5β-[(E)-5-Hydroxy-3-Methyl-3-Pentenyl]-5,6α,8Aα-Trimethyl-1-Methylenenaphthalen-2α-Ol undergoes rigorous analytical testing to ensure identity, purity, and consistency. Our quality assurance protocols are designed to meet the stringent requirements of research and development applications. A comprehensive Certificate of Analysis (COA) detailing purity (typically by HPLC), chiral purity, and impurity profile is provided with each shipment to support your quality and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) in a cool, dry place at 2-8°C to minimize oxidation and ensure long-term stability. The container should be kept in a well-ventilated area away from heat and incompatible materials.
