Quality Control

Our production of 3-Hydroxy-4-[(2-Methoxy-4-Nitrophenyl)Azo]-n-Naphthylnaphthalene-2-Carboxamide adheres to stringent quality management protocols to ensure batch-to-batch consistency and purity. Each lot undergoes comprehensive analytical testing, including HPLC for assay and impurity profiling. Certificates of Analysis (COA) documenting identity, purity, and physical characteristics are provided with every shipment to support your quality assurance processes.

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 degradation from atmospheric moisture. Keep away from incompatible materials.
