Quality Control

Our Iron Dihydroxide is produced under stringent quality management protocols. Each batch undergoes comprehensive analytical testing to ensure it meets precise chemical and physical specifications. We provide full traceability and Certificates of Analysis (COA) are available for all shipments, detailing key parameters such as assay, impurity profiles, and physical characteristics to support your quality assurance processes.

Storage

Preserve in a tightly closed container, protected from light. Due to its property of being easily oxidized, this material should be stored under an inert atmosphere (e.g., nitrogen or argon) in a cool, dry, and well-ventilated area. Recommended storage temperature is between 15°C and 25°C. Keep away from strong oxidizing agents.
