Quality Control

Our Corilagin is produced under strict quality management protocols to ensure batch-to-batch consistency and high purity, suitable for research and analytical applications. Each lot is accompanied by a comprehensive Certificate of Analysis (COA) detailing purity, identity confirmation via spectroscopic methods, and impurity profiles. We can supply material that meets in-house specifications for research use and can discuss custom synthesis to meet specific pharmacopeial or analytical standards.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). Due to its sensitivity to oxidation, it is recommended to store the product under an inert atmosphere for long-term preservation and to minimize headspace in opened containers.
