Quality Control

Our production of 1-[2-[[4-[(2-Chloro-4-Nitrophenyl)Azo]Phenyl]Ethylamino]Ethyl]Pyridinium Hydrogen Sulphate adheres to a stringent quality management system. Every batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation, to ensure consistency and compliance with customer specifications. Certificates of Analysis (COA) detailing all critical parameters are provided with each shipment to guarantee traceability and 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 degradation from atmospheric moisture. Keep away from incompatible materials such as strong oxidizing agents.
