Quality Control

Our 4H-1-Benzopyran-4-One, 2-(3,5-Dibromo-4-Hydroxyphenyl)-6-Hydroxy-3-Methyl- is produced under a strict quality management system. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation via spectroscopic methods (IR, NMR), to ensure it meets exacting standards for research and development. Certificates of Analysis (COA) detailing batch-specific results are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at a controlled room temperature (typically 15-25°C). Due to its nature as an organic compound that is easily oxidized, long-term storage under an inert atmosphere (e.g., nitrogen or argon) is recommended for optimal stability. Keep away from strong oxidizing agents.
