Quality Control

Our L-Asparagine, N-Methyl-, Methylester (9Ci) is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including chiral purity verification and impurity profiling by HPLC, to ensure it meets the exacting standards required for research and development applications. A detailed Certificate of Analysis (COA) providing batch-specific results for identity, purity, and related substances is supplied with every order.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, 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 opening to prevent degradation from atmospheric moisture.
