Quality Control

Our production of this reactive dye intermediate adheres to strict quality management systems. Every batch is analyzed to ensure consistency in reactivity, color value, and impurity profile. Certificates of Analysis (COA) documenting key parameters such as assay purity, sulfonate content, and heavy metal limits are available upon request to support your quality assurance protocols.

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 nature, the container must be kept sealed to prevent moisture absorption, which can affect reactivity and stability.
