Quality Control

Our Ethyl 2-[(6-Oxo-7,8,9,10-tetrahydrobenzo[C]chromen-3-yl)oxy]propanoate is manufactured under a strict quality management system. Every batch undergoes comprehensive analytical testing, including HPLC, NMR, and MS, to ensure identity, purity, and consistency. A detailed Certificate of Analysis (COA) is provided with each shipment, confirming compliance with agreed specifications. We support cGMP and ISO standards for pharmaceutical and industrial applications.

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 hygroscopic nature, the container must be kept tightly sealed after each use to prevent moisture absorption. Keep away from incompatible materials.
