Quality Control

Our Leonoside B is produced under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including HPLC for purity, spectroscopic identification (IR, NMR, MS), and residual solvent analysis to ensure it meets the stringent requirements for research and development. A detailed Certificate of Analysis (COA) is provided with every shipment, confirming identity, purity, and compliance with relevant specifications.

Storage

Preserve in a tightly closed container, protected from light. For long-term stability, store at -20°C or below in a desiccated environment. The product is hygroscopic (moisture-sensitive). Allow the vial to equilibrate to room temperature before opening to prevent condensation.
