Quality Control

Our Fumaric Acid, Copper Salt is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing, including assay, heavy metal screening, and loss on drying, to ensure it meets precise specifications. A Certificate of Analysis (COA) documenting purity, physical characteristics, and compliance is provided with every shipment to guarantee traceability and performance for your 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 sealed immediately after use to prevent absorption of atmospheric moisture, which can affect product quality and handling properties.
