Quality Control

Our (S)-5-[[(1S,4Aα)-3α-Acetoxydecahydro-6α-Hydroxy-2α,5,5,8Aβ-Tetramethylnaphthalen-1β-Yl]Methyl]-4-Methylfuran-2(5H)-One is produced under strict quality management systems. Each batch undergoes comprehensive analytical testing including HPLC, NMR, and chiral purity analysis to ensure identity, potency, and purity meet stringent specifications. A detailed Certificate of Analysis (COA) is provided with every shipment, confirming compliance with customer requirements and internal standards.

Storage

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