Quality Control

Our production of 2-[4-[[4-[[4-[(2-Cyanoethyl)Ethylamino]Phenyl]Azo]-2-Methylphenyl]Azo]Phenoxy]Ethyl Sodium Sulphate adheres to stringent quality management protocols to ensure batch-to-batch consistency and high purity. Each lot is analyzed against comprehensive specifications, including identity, assay, and impurity profiles. A Certificate of Analysis (COA) detailing all test results is provided with every shipment to support your quality assurance and regulatory compliance needs.

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 to prevent absorption of atmospheric moisture, which can affect product performance and stability.
