Quality Control

Our production of 4-[[5-(Anilino)Carbonyl-2-Methoxyphenyl]Azo]-3-Hydroxynaphthalene-2-Carboxamide adheres to stringent quality management protocols to ensure batch-to-batch consistency and purity. Every lot undergoes comprehensive analytical testing, including HPLC for assay and impurity profiling, to meet exacting customer specifications. Certificates of Analysis (COA) detailing all critical parameters are provided and available upon request to support your quality assurance and regulatory needs.

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 after opening to prevent moisture absorption, which can affect product performance. Keep away from incompatible materials.
