Quality Control

Our Ellagic Acid is produced under strict quality management systems to ensure batch-to-batch consistency and high purity. Each lot is accompanied by a comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles. We can supply material compliant with various pharmacopeial standards (e.g., USP-NF) upon request, ensuring it meets the rigorous demands of pharmaceutical and research applications.

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 light-sensitive and easily oxidized nature, it is recommended to handle under an inert atmosphere for long-term storage and to minimize headspace in opened containers.
