Quality Control

Our production of this reactive dye intermediate adheres to strict quality management systems. Every batch is subjected to comprehensive analytical testing, including HPLC for purity and identity confirmation, to ensure consistent performance and batch-to-batch reliability. A detailed Certificate of Analysis (COA) specifying purity, impurity profile, and other critical parameters is provided with each shipment.

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 tightly sealed to prevent absorption of atmospheric moisture, which can affect product stability and performance.
