Quality Control

Our (1S,3'S,4'S,4'aR)-1,2,2',3,3',4,4',9,9',9a-Decahydro-1β,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 a strict quality management system. Every batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation via spectroscopic methods, to ensure it meets exacting research-grade standards. A detailed Certificate of Analysis (COA) is provided with each shipment, documenting all critical quality parameters.

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 nature, the container must be kept tightly sealed in a dry environment to prevent moisture absorption. For long-term storage, consider desiccants or an inert atmosphere.
