Quality Control

Our 3-Epimeliasenin B is produced under strict quality management protocols to ensure batch-to-batch consistency and high purity, suitable for sensitive research applications. Each lot is accompanied by a comprehensive Certificate of Analysis (COA) detailing purity, identity confirmation, and impurity profiles. We adhere to relevant guidelines for research chemicals, ensuring reliable and traceable material for your scientific work.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (typically 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 an inert atmosphere.
