Quality Control

Our Fumaric Acid Monoethyl Ester, Magnesium Salt is produced under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure it meets precise specifications for identity, purity, and composition. Certificates of Analysis (COA) documenting results for assay, heavy metals, residual solvents, and other critical parameters are available upon request. We adhere to cGMP principles where applicable to support our customers in pharmaceutical and high-purity applications.

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 absorption of atmospheric moisture. For long-term storage, consider using an inert atmosphere to minimize potential oxidation.
