Quality Control

Our Eleutheroside B is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity, identity confirmation by IR and NMR, and residual solvent analysis, to ensure it meets high-grade specifications suitable for research and industrial applications. A detailed Certificate of Analysis (COA) is provided with every shipment to guarantee traceability and compliance.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). This product is hygroscopic (moisture-sensitive) and light-sensitive; therefore, containers must be kept tightly sealed and desiccated after opening to maintain stability and purity.
