Quality Control

Our Disodium 5-[[4'-[[7-(Acetylamino)-1-Hydroxy-3-Sulphonato-2-Naphthyl]Azo][1,1'-Biphenyl]-4-Yl]Azo]Salicylate is produced under a stringent quality management system. Every batch undergoes rigorous analytical testing to ensure high purity, consistent composition, and batch-to-batch reliability. Comprehensive Certificates of Analysis (COA) detailing purity, identity, and impurity profiles are provided to guarantee compliance with your specific application requirements.

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.
