Quality Control

Our production of Pentasodium 2-[[4-Chloro-6-[[8-Hydroxy-3,6-Disulphonato-7-[(1-Sulphonato-2-Naphthyl)Azo]-1-Naphthyl]Amino]-1,3,5-Triazin-2-Yl]Amino]-5-Sulphonatobenzoate adheres to a stringent quality management system. Every batch undergoes rigorous analytical testing to ensure high purity, consistent performance, and traceability. Certificates of Analysis (COA) detailing purity, impurity profile, and other critical parameters are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at 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.
