Quality Control

Our 7-Hydroxy-4-Propyl-2H-Chromen-2-One is manufactured under a strict quality management system. Every batch undergoes comprehensive analytical testing, including HPLC, GC, and NMR, to ensure identity, purity, and consistency. We provide a detailed Certificate of Analysis (COA) with each shipment, documenting all critical quality parameters. Our production adheres to cGMP principles where applicable, ensuring reliability for research and scale-up processes.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place 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.
