Quality Control

Our Sodium 5-[(5-Chloro-2-Hydroxyphenyl)Azo]-6-Hydroxynaphthalene-2-Sulphonato(3-)]Hydroxychromate(1-) is manufactured under a strict quality management system. Every batch undergoes comprehensive analytical testing, including assay, impurity profiling, and identity confirmation, to ensure it meets exacting industry specifications. A detailed Certificate of Analysis (COA) documenting purity, physical characteristics, and test results is provided with each shipment to guarantee traceability and consistency.

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 after opening to prevent absorption of atmospheric moisture, which can affect product quality and handling properties.
