Quality Control

Our L-Norvaline, 4-Oxo- (9Ci) is produced under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including chiral purity verification and impurity profiling by HPLC, to ensure it meets the high standards required for research and synthesis applications. A Certificate of Analysis (COA) detailing specific results for identity, purity, and related substances is provided with every shipment.

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 use to prevent degradation from atmospheric moisture.
