Quality Control

Our 2,5-Dichloro-4-[[2-(Dibutylamino)-4-Methyl-6-[[2-(4-Sulfophenyl)Ethyl]Amino]-5-Pyrimidinyl]Azo]Benzenesulfonic Acid is manufactured under a strict quality management system to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including HPLC for assay and impurity profile determination. Certificates of Analysis (COA) documenting identity, purity, and related substances are provided with every shipment 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 degradation from atmospheric moisture. Keep away from incompatible materials.
