Quality Control

Our Ehretioside B is produced under strict quality management protocols to ensure batch-to-batch consistency and high purity suitable for research applications. Each lot is accompanied by a comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles, generated using validated analytical methods including HPLC and NMR. We are committed to meeting the stringent requirements of research and development laboratories.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed in a dry environment to prevent degradation. For long-term storage, consider desiccants or inert atmosphere.
