Quality Control

Every batch of 1(2H)-Pentalenone,4-Acetyl-5-Ethylhexahydro-3A-Hydroxy-6A-Methyl-,(3Ar,4S,5R,6Ar)-Rel-(9Ci) is manufactured under strict quality management systems. Our products undergo rigorous analytical testing, including chiral purity analysis, to ensure compliance with research and development grade standards. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with each shipment to guarantee traceability and batch-to-batch consistency.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (typically 15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after each use to prevent degradation from atmospheric moisture. For long-term storage, consider using desiccants.
