Quality Control

Our 4H-1-Benzopyran-2-Carboxylic Acid, 7-Hydroxy-8-Nitro-4-Oxo-, Ethyl Est Er is produced under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation via FT-IR and NMR, to ensure it meets the high standards required for research and development applications. A Certificate of Analysis (COA) detailing all specifications is provided with every shipment to guarantee traceability and consistency.

Storage

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