Quality Control

Our Diammonium Fumarate is manufactured under a stringent quality management system. Each batch is tested to ensure it meets exacting specifications for identity, purity, and composition. Certificates of Analysis (COA) documenting results for all critical parameters are available upon request to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed to prevent moisture absorption, which can affect product quality and flow characteristics.
