Quality Control

Our production of 4H-1-Benzopyran-4-One, 5-Hydroxy-3,7-Bis(2-Hydroxyethoxy)-2-[3-Hydroxy-4-(2-Hydroxyethoxy)Phenyl]- adheres to stringent quality management protocols. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation via spectroscopic methods (IR, NMR), to ensure compliance with exacting industry standards. Certificates of Analysis (COA) detailing all specifications are provided and can be tailored to meet specific customer or regulatory requirements.

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 opening to minimize exposure to atmospheric moisture. For long-term storage, consider using desiccants.
