Quality Control

Our (3R,3'R,4S,4'S,4aS,4'aS)-2,2',3,3',4,4',9,9'-Octahydro-1,1',4,4',8,8'-hexahydroxy-3,3'-dimethyl-9,9'-dioxo-7,7'-bi(4aH-xanthene)-4a,4'a-dicarboxylic acid dimethyl ester is produced under strict quality management systems. Every batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation, to ensure it meets the high standards required for research and development. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with each shipment to guarantee traceability and consistency.

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 and light-sensitive nature, the container must be kept tightly sealed in a dry environment and handled under conditions that minimize exposure to moisture and ambient light. For long-term storage, consider using desiccants and storing under an inert atmosphere to prevent oxidation.
