Quality Control

Our 1H-2-Benzopyran-5,8-Dione, 7-Methoxy-1,3-Dimethyl- (9Ci) is produced under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including HPLC for purity and spectroscopic identification (IR, NMR), to ensure it meets exacting research-grade specifications. A detailed Certificate of Analysis (COA) is provided with every shipment to guarantee traceability and compliance with your project requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, 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.
