Quality Control

Our Sodium 2-[4-Hydroxy-3-[(2-Hydroxy-1-Naphthyl)Azo]Benzoyl]Benzoate is manufactured under a strict quality management system. Every batch undergoes rigorous analytical testing to ensure it meets precise chemical and physical specifications. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with each shipment to guarantee batch-to-batch consistency and 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 sealed to prevent absorption of atmospheric moisture.
