Quality Control

Our production of 3-[[4-[[2-Chloro-4-(Methylsulphonyl)Phenyl]Azo]-3-Methylphenyl]Ethylamino]Propiononitrile adheres to stringent quality management protocols to ensure batch-to-batch consistency and purity. Every lot undergoes comprehensive analytical testing, including HPLC for assay and impurity profiling. A Certificate of Analysis (COA) detailing identity, purity, and related substances is provided with each shipment to guarantee compliance with your technical specifications.

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 to prevent degradation from atmospheric moisture. Keep away from incompatible materials such as strong oxidizing agents.
