Quality Control

Our production of this anthraquinone intermediate adheres to strict quality management protocols to ensure batch-to-batch consistency and high purity. Each lot is analyzed using advanced techniques including HPLC, NMR, and mass spectrometry to confirm identity and assay. A comprehensive Certificate of Analysis (COA) detailing purity, impurity profile, and physical characteristics is provided with every shipment to support your quality assurance and regulatory 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 (moisture-sensitive) nature, the container must be kept sealed to prevent absorption of atmospheric moisture. Keep away from incompatible materials.
