Quality Control

Our L-Alanine, n-Ethylidene- (9Ci) is produced under stringent quality management systems. Each batch undergoes comprehensive analytical testing, including chiral purity verification by HPLC, to ensure it meets the high standards required for research and development applications. A Certificate of Analysis (COA) detailing identity, purity, and specific test results 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 opening to prevent degradation from atmospheric moisture.
