Quality Control

Our Sodium m-[(p-Aminophenyl)Azo]Benzenesulphonate is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure it meets high-purity standards and consistent performance for synthesis. Key parameters such as assay, impurity profile, and solubility are verified. A Certificate of Analysis (COA) documenting these results is 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, well-ventilated area at room temperature (typically 15-25°C). Keep away from strong oxidizing agents. Due to its light-sensitive nature, prolonged exposure to direct light should be avoided to maintain product integrity.
