Quality Control

Our Tetrasodium 7-[[4-[[(2,3-Dichloro-6-Quinoxalinyl)Carbonyl]Amino]-5-Sulphonato-1-Naphthyl]Azo]Naphthalene-1,3,5-Trisulphonate is produced under a strict quality management system to ensure batch-to-batch consistency and high purity. The product undergoes rigorous analytical testing, including HPLC for assay and impurity profiling. Certificates of Analysis (COA) documenting identity, purity, and relevant specifications 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 each use to prevent absorption of atmospheric moisture, which can affect product quality and handling properties.
