Quality Control

Our Pennogenin3-o-α-L-Rhamnopyranosyl-(1→2)-[α-L-Rhamnopyranosyl-(1→4)]-β-D-Glucopyranoside is produced under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity, spectroscopic identification (IR, NMR, MS), and residual solvent analysis to ensure it meets high-grade reference material standards. A detailed Certificate of Analysis (COA) providing full specifications and test results is available for every lot.

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 nature, the container should be kept in a desiccated environment to prevent moisture absorption. For long-term storage, consider storing under an inert atmosphere.
