Quality Control

Our n-(1-Oxooctadecyl)-L-Glutamic Acid is manufactured under a strict quality management system. Every batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation, to ensure it meets precise specifications. A Certificate of Analysis (COA) detailing all test results is provided with each shipment, guaranteeing traceability and compliance with your technical and regulatory requirements.

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 nature, the container must be kept tightly sealed after opening to minimize exposure to atmospheric moisture. Keep away from incompatible materials such as strong oxidizing agents.
