Quality Control

Our Delphinidin-3-o-Rhamnoside Chloride is produced and handled under strict quality protocols. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation (IR, UV-Vis), to ensure it meets the high standards required for research and analytical applications. A detailed Certificate of Analysis (COA) is provided with every shipment, documenting batch-specific results.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at 2-8°C (refrigerated) or as indicated on the label or COA. This compound is hygroscopic (moisture-sensitive); ensure the container is sealed tightly after each use to minimize exposure to atmospheric humidity.
