Quality Control

Our production of this anthraquinone intermediate adheres to strict quality management protocols to ensure batch-to-batch consistency and purity. Each lot is analyzed using advanced techniques including HPLC and spectroscopic methods to verify identity and quantify impurities. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and specific impurity profiles 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 a controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed to prevent moisture absorption, which can affect stability and performance. Keep away from incompatible materials.
