Quality Control

Our Lithium Ethyl Fumarate is manufactured under a strict quality management system. Every batch undergoes comprehensive analytical testing, including assay, impurity profiling, and identification, to ensure it meets precise customer specifications and high-purity standards. A Certificate of Analysis (COA) detailing all test results is provided with each shipment and is available upon request.

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 to prevent moisture absorption. Keep away from incompatible materials such as strong acids and oxidizing agents.
