Quality Control

Our 2,5-Dimethyl-8,10-Dihydroxy-4H-Naphtho[1,2-B]Pyran-4-One is produced under a strict quality management system. Each batch undergoes rigorous analytical testing, including HPLC, NMR, and IR spectroscopy, to ensure identity, purity, and consistency. Certificates of Analysis (COA) detailing all specifications are provided and can be tailored to meet specific customer requirements for research or commercial use.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its light-sensitive nature and propensity for oxidation, it is recommended to handle under an inert atmosphere for long-term storage and to minimize headspace in opened containers.
