Quality Control

Our Trisodium 2-[4-(4-Amino-2,5-Dimethoxy-Phenyl)Diazenyl-6-Sulfonato-Naph Thalen-1-Yl]Diazenylbenzene-1,4-Disulfonate is produced under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure it meets precise specifications for purity, color value, and chemical identity, consistent with industry standards for dye intermediates. Certificates of Analysis (COA) are available upon request to support your quality assurance and regulatory compliance needs.

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 after opening to prevent absorption of atmospheric moisture, which can affect product quality and handling properties.
