Quality Control
Our Levetiracetam Impurity 31 is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation via spectroscopic methods (IR, NMR, MS), to ensure compliance with pharmaceutical reference standard requirements. Certificates of Analysis (COA) detailing batch-specific results are provided and available upon request.
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.
