Quality Control

Our L-3-Methylaspartic Acid is produced under a strict quality management system. Each batch undergoes comprehensive analytical testing, including HPLC for purity and chiral purity assessment, to ensure it meets the high standards required for research and synthesis. A detailed Certificate of Analysis (COA) is provided with every shipment, confirming identity, purity, and specific attributes.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed to minimize exposure to atmospheric moisture. For long-term storage, consider using a desiccant.
