Quality Control

Our (25R)-3β-(2-O,4-o-Di-α-L-Rhamnopyranosyl-β-D-Glucopyranosyloxy)-17-Hydroxyspirosta-5-Ene is produced under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity and spectroscopic methods for structural confirmation, to ensure it meets the high standards required for research and development. Certificates of Analysis (COA) with detailed chromatographic and spectral data are provided to guarantee traceability and batch-to-batch consistency.

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 hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed in a desiccated environment to prevent degradation. For long-term storage, consider inert atmosphere conditions.
