Quality Control

Our Sodium p-[(4-Amino-2,5-Xylyl)Azo]Benzenesulphonate is produced under a strict quality management system. Each batch undergoes comprehensive analytical testing to ensure high purity and consistency, meeting the stringent requirements of industrial dye synthesis. A Certificate of Analysis (COA) detailing identity, assay, and impurity profiles is provided with every shipment.

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 tightly sealed after opening to prevent moisture absorption, which can affect product quality.
