Quality Control

Our (2R,3R,4Ar)-2,3,4,4A-Tetrahydro-2,3,7-Trihydroxy-9-Methoxy-4A-Methyl-6H-Dibenzo[B,D]Pyran-6-One is produced under strict quality management systems to ensure batch-to-batch consistency and high purity. All products undergo rigorous analytical testing, including HPLC, NMR, and MS, to confirm identity and purity. Certificates of Analysis (COA) detailing all specifications are provided with each shipment and are available upon request.

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 desiccants or inert atmosphere.
