Quality Control

Our 1,8-Dihydroxy-2,5-dinitroanthraquinone is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure it meets precise specifications for identity, purity, and impurity profiles. A comprehensive Certificate of Analysis (COA) detailing results for assay, related substances, and physical properties is provided with every shipment to guarantee traceability and compliance.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at a controlled room temperature (15-25°C). Due to its light-sensitive nature and propensity for oxidation, it is recommended to store the material under an inert atmosphere for long-term preservation and to minimize exposure to air and moisture.
