Quality Control

Our 5-[(R)-1-Acetoxyethyl]-5'-Acetyl-6,6'-Dimethyl-1,1',8,8'-Tetrahydroxy-2,2'-Bianthraquinone is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and chiral purity assessment, to ensure high chemical and isomeric consistency. Certificates of Analysis (COA) detailing identity, purity, and impurity profiles are provided with every shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a 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. For long-term storage, consider the use of desiccants.
