Quality Control

Our (1R,13R)-1,3,4,6,7,9,10,11-Octahydro-4α,5,10β,12,13-Pentahydroxy-3α,7α-Dimethyl-6,11-Dioxo-1β,4-Ethanonaphtho[2,3-C:6,7-C']Dipyran-9β-Acetic Acid Methyl Ester is produced under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation via spectroscopic methods. Certificates of Analysis (COA) detailing batch-specific results are available upon request to ensure full traceability and compliance with your research or development specifications.

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 to prevent product degradation. For long-term storage, consider desiccants or an inert atmosphere.
