Quality Control

Our production of Trisodium 3-[[4-(Allylsulphonyl)Phenyl]Azo]-4-Amino-6-[[5-[(4,6-Dichloro-1,3,5-Triazin-2-Yl)Amino]-2-Sulphonatophenyl]Azo]-5-Hydroxynaphthalene-2,7-Disulphonate adheres to stringent quality protocols to ensure batch-to-batch consistency and performance reliability. Every lot is analyzed for critical parameters including purity, reactive group content, and impurity profile. Certificates of Analysis (COA) documenting these results 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 nature, the container must be kept tightly sealed to prevent moisture absorption, which can affect reactivity and stability.
