Quality Control

Our Cyanidin-3-o-Rhamnoside Chloride is produced and tested under a strict quality management system. Each batch is analyzed to confirm identity, purity, and conformity to specifications using advanced techniques like HPLC and spectroscopy. A comprehensive Certificate of Analysis (COA) detailing all test results is provided with every shipment. We can support compliance requirements for food-grade (FCC) and nutraceutical applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at 2-8°C (refrigerated) or under inert atmosphere for long-term stability, as the compound is light-sensitive and easily oxidized. Keep away from strong oxidizing agents.
