Quality Control

Our (-)-Lyoniresinol is produced and handled under strict quality management protocols to ensure batch-to-batch consistency and high purity suitable for research and development. Each lot undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation via spectroscopic methods. A detailed Certificate of Analysis (COA) is provided with every shipment, documenting key specifications and test results.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after each use to prevent degradation from atmospheric moisture. For long-term storage, consider using desiccants.
