Quality Control

Our 5,9-Dihydroxy-3,3-Dimethylpyrano[3,2-A]Xanthen-12(3H)-One is produced under strict quality management protocols. Each batch undergoes rigorous analytical testing, including HPLC for purity and spectroscopic methods for structural confirmation, to ensure it meets the high standards required for research and industrial synthesis. Certificates of Analysis (COA) detailing batch-specific results 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 light-sensitive nature and propensity to be easily oxidized, it is recommended to handle under an inert atmosphere for long-term storage and to minimize headspace in opened containers.
