Quality Control

Our production of this azo dye intermediate adheres to strict quality management systems. Every batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation, to ensure it meets the high standards required for industrial synthesis. A detailed Certificate of Analysis (COA) is provided with each shipment, documenting key parameters such as assay, impurity profile, and physical characteristics.

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). Keep away from incompatible materials such as strong oxidizing agents. Due to its light-sensitive nature, prolonged exposure to direct light should be avoided to maintain product integrity.
