Quality Control

Our (25R)-3β-(4-o-α-L-Rhamnopyranosyl-β-D-Glucopyranosyloxy)Spirosta-5-Ene is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation (IR, NMR), to ensure it meets the high standards required for research and development. A detailed Certificate of Analysis (COA) is provided with every shipment, documenting critical parameters such as assay, related substances, and residual solvents.

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 compound is hygroscopic (moisture-sensitive); therefore, the container must be kept tightly sealed in a dry environment to prevent degradation. For long-term storage, consider desiccants or inert atmosphere.
