Quality Control

Our production of this advanced dye intermediate adheres to strict quality management systems. Every batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation, to ensure consistency and reliability for your synthesis processes. A detailed Certificate of Analysis (COA) is provided with each shipment, documenting key parameters such as assay, impurity profile, and solubility.

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 (moisture-sensitive) nature, the container must be kept sealed to prevent absorption of atmospheric moisture, which can affect product performance.
