Quality Control

Our (3S,5S,11E)-3,4,5,6,9,10-Hexahydro-5,14,16-Trihydroxy-3-Methyl-1H-2-Benzoxacyclotetradecin-1,7(8H)-Dione is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC, NMR, and MS, to ensure identity, purity, and consistency. Certificates of Analysis (COA) detailing all specifications are provided with every shipment to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed in a dry environment. For long-term storage, consider storing under an inert atmosphere to prevent oxidation.
