Quality Control

Our Trisodium 2-[[6-[(5-Chloro-2,6-Difluoropyrimidin-4-Yl)Amino]-1-Hydroxy-3-Sulphonato-2-Naphthyl]Azo]Toluene-3,5-Disulphonate is produced under a strict quality management system. Every batch undergoes rigorous analytical testing to ensure high purity and consistent performance as a dye intermediate. Specifications are aligned with industry standards for fine chemicals. Certificates of Analysis (COA) detailing purity, identity, and impurity profiles 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, 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 opening to prevent absorption of atmospheric moisture, which can affect product quality and handling properties.
