Quality Control

Our Sodium m-[[4-[[2-Amino-5-Cyano-6-[[2-(2-Hydroxyethoxy)Ethyl]Amino]-4-Methyl-3-Pyridyl]Azo]-2,5-Xylyl]Azo]Benzenesulphonate is manufactured under a strict quality management system. Every batch undergoes rigorous analytical testing to ensure consistent purity, identity, and performance as a dye intermediate. Certificates of Analysis (COA) with detailed HPLC/UV-Vis data are provided to guarantee compliance with your technical specifications and support your own quality assurance protocols.

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 nature, the container must be kept tightly sealed after opening to prevent moisture absorption, which can affect purity and handling properties.
