Quality Control

Our 8-Hydroxy-2-Methoxy-9-Oxo-9H-Xanthene-1-Carboxylic Acid Methyl Ester is manufactured under a strict quality management system. Every batch undergoes comprehensive analytical testing, including HPLC, NMR, and IR spectroscopy, 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 standards for pharmaceutical applications and can provide regulatory support documentation as required.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (typically 15-25°C). Keep away from incompatible materials. Due to its light-sensitive nature, handling and packaging should minimize exposure to direct light.
