Quality Control

Our Trisodium 3-[[4-[[4-[(2,5,6-Trichloropyrimidin-4-Yl)Amino]Phenyl]Azo]Phenyl]Azo]Naphthalene-1,5,7-Trisulphonate is produced under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation, to ensure it meets precise specifications for use in sensitive synthesis processes. Certificates of Analysis (COA) documenting batch-specific results 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 room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed to prevent absorption of atmospheric moisture, which can affect product performance and stability.
