Quality Control

Our production of Disodium 5-[[4-[[[4-[(7-Amino-1-Hydroxy-3-Sulphonato-2-Naphthyl)Azo]Phenyl]Amino]Carbonyl]Phenyl]Azo]Salicylate adheres to stringent quality management protocols to ensure batch-to-batch consistency and purity. Each lot undergoes comprehensive analytical testing, including HPLC for assay and impurity profiling. Certificates of Analysis (COA) detailing purity, identity, and specific test results are provided with every shipment 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 a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept sealed when not in use to prevent degradation from atmospheric moisture. Keep away from incompatible materials.
