Quality Control

Our Sodium 5,7-Dihydroxy-4-Oxo-3-Phenyl-4H-1-Benzopyran-2-Carboxylate is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation via IR and NMR spectroscopy, to ensure it meets exacting standards for research and industrial use. Certificates of Analysis (COA) with complete batch data are available upon request.

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 hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after each use to prevent degradation. For long-term storage, consider using desiccants or storing under an inert atmosphere to minimize oxidation.
