Quality Control

Our n-(4-Chloro-2-Methylphenyl)-3-Hydroxy-4-[(2-Methylphenyl)Azo]Naphthalene-2-Carboxamide is manufactured under a strict quality management system. Every batch undergoes rigorous analytical testing to ensure high purity, consistent performance, and compliance with customer specifications. Comprehensive Certificates of Analysis (COA) detailing identity, purity, and impurity profiles are provided with each 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 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. Keep away from incompatible materials such as strong oxidizing agents.
