Quality Control

Our Methoxyapigeninidin Chloride, 7-(Rg) is produced and handled under a strict quality management system. Each batch undergoes comprehensive analytical testing to ensure identity, purity, and consistency. A detailed Certificate of Analysis (COA) documenting purity (typically by HPLC), identification (by spectroscopic methods), and other critical parameters is provided with every shipment to support your research and compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed in a dry environment to prevent moisture absorption. For long-term storage, consider desiccants or inert atmosphere.
