Quality Control

Our Sodium m-[[[4-(Benzothiazol-2-Ylazo)-m-Tolyl]Ethylamino]Methyl]Benzenesulphonate is produced under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure consistent purity, color strength, and chemical identity. Certificates of Analysis (COA) detailing specifications such as assay, impurity profile, and physical characteristics are provided to guarantee it meets the exacting standards required for industrial dye synthesis.

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 sealed when not in use to prevent absorption of atmospheric moisture, which can affect product performance.
