Quality Control

Our [(25R)-5α-Spirostan-3β-Yl]4-o-(β-D-Galactopyranosyl)-β-D-Glucopyranoside is produced under a strict quality management system. Each batch undergoes rigorous analytical testing including HPLC for purity, IR and NMR for structural confirmation, and tests for residual solvents and heavy metals to ensure it meets the exacting standards required for research and development. A comprehensive Certificate of Analysis (COA) is provided with every shipment.

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 dry environment to prevent degradation. For long-term storage, consider desiccants or inert atmosphere.
