Quality Control

Our production of 2-[[4-[(2-Chloro-4-Nitrophenyl)Azo]Phenyl]Ethylamino]Ethyl](2-Hydroxypropyl)Dimethylammonium Sulphate adheres to stringent quality management systems to ensure batch-to-batch consistency and purity. All materials are tested against rigorous in-house specifications, which typically include identity confirmation, assay, and impurity profiling. A Certificate of Analysis (COA) detailing the results is provided with every shipment to support your quality assurance protocols.

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 absorption of atmospheric moisture, which can affect product performance.
