Quality Control

Our production of this reactive dye intermediate adheres to strict quality management systems. Every batch undergoes comprehensive analytical testing, including HPLC for purity and isomer content, titration for active moiety assay, and spectroscopic identification (IR/UV-Vis). We provide a detailed Certificate of Analysis (COA) with each shipment, ensuring traceability and compliance with your technical specifications. Our quality commitment supports the demanding requirements of the global textile chemical supply chain.

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). This material is hygroscopic (moisture-sensitive); therefore, the container must be kept tightly sealed after opening to prevent absorption of atmospheric moisture, which can affect performance. Keep away from incompatible materials such as strong oxidizing agents.
