Quality Control

Our Quercetin 3-o-Robibioside is produced and handled under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation (IR, UV), to ensure it meets the high standards required for research and industrial applications. A Certificate of Analysis (COA) detailing all specifications is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at controlled room temperature (15-25°C). This compound is hygroscopic (moisture-sensitive); therefore, the container must be kept tightly sealed in a dry environment to prevent absorption of moisture.
