Quality Control

Our Macrostemonoside E is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing, including HPLC for purity, NMR and MS for structural confirmation, and tests for residual solvents and heavy metals to ensure it meets the stringent requirements for research and reference standards. A detailed Certificate of Analysis (COA) is provided with every shipment, guaranteeing traceability and compliance with your specifications.

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) and must be kept in a desiccated environment to maintain stability and purity. For long-term storage, consider storing under an inert atmosphere.
