Quality Control

Our production of Trisodium 5-Amino-8-[[4-[[4-[(4,6-Dichloro-1,3,5-Triazin-2-Yl)Amino]-2-Sulphonatophenyl]Azo]Phenyl]Amino]-9,10-Dihydro-9,10-Dioxoanthracene-1,6-Disulphonate adheres to stringent quality protocols to ensure batch-to-batch consistency and performance reliability. All materials undergo rigorous analytical testing, including HPLC for purity and identity confirmation. Certificates of Analysis (COA) detailing purity, assay, and impurity profiles are provided with every shipment to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after each use to prevent degradation from atmospheric moisture. Keep away from incompatible materials.
