Quality Control

Our (1S,3'R,4'S,4'aS)-1,2,2',3,3',4,4',9,9',9a-Decahydro-1,1',4α,4',8,8',9aα-heptahydroxy-3α,3'-dimethyl-9,9'-dioxo-7,7'-bi(4aH-xanthene)-4aβ,4'a-dicarboxylic acid dimethyl ester is produced under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity and chiral integrity, NMR, and MS for structural confirmation, to ensure it meets the exacting standards required for research and synthesis. A detailed Certificate of Analysis (COA) is provided with every shipment, documenting key parameters such as assay, chiral purity, and impurity profile.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed to minimize exposure to atmospheric moisture. For long-term storage, consider using desiccants or an inert atmosphere.
