Quality Control

Our production of this advanced colorant adheres to strict quality management protocols. Every batch undergoes comprehensive analysis to ensure consistency in color value, purity, and functional group content. Certificates of Analysis (COA) detailing key specifications such as assay, sulfonation degree, and impurity profile are provided with each shipment to guarantee it meets your technical requirements.

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 tightly sealed after opening to prevent moisture absorption, which can affect performance.
