Quality Control

Our production of 4-[(4-Chloro-2-Methylphenyl)Azo]-3-Hydroxy-n-(2-Methoxyphenyl)Naphthalene-2-Carboxamide adheres to stringent quality management protocols. Every batch undergoes rigorous analytical testing to ensure consistent purity, color strength, and performance characteristics. Certificates of Analysis (COA) documenting key parameters such as assay, impurity profile, and physical properties are available upon request 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 to prevent absorption of atmospheric moisture, which could affect product performance.
