Quality Control

Our Dihydroxyfumaric Acid is produced and tested under a rigorous quality management system. Each batch is analyzed to ensure it meets high-purity standards suitable for research and industrial use. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with every shipment to guarantee traceability and consistency.

Storage

Preserve in a tightly closed container, protected from light. Due to its hygroscopic and easily oxidized nature, store in a cool, dry place (15-25°C) under an inert atmosphere (e.g., nitrogen or argon) for long-term stability. Keep the container tightly sealed when not in use to minimize exposure to moisture and air.
