Quality Control

Every batch of our azo dye intermediate is subjected to rigorous analytical testing to ensure it meets the stringent purity and consistency standards demanded by the colorant industry. Our quality assurance protocols include advanced chromatographic methods to verify chemical identity and impurity profiles. A Certificate of Analysis (COA) detailing specific batch results is provided with each shipment to guarantee traceability and compliance with your specifications.

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 and stability.
