Quality Control

Our production of 5-[[4-(Benzylmethylamino)Phenyl]Azo]-1,2,3-Trimethyl-1H-Pyrazolium Methyl Sulphate adheres to stringent quality management protocols to ensure batch-to-batch consistency and purity. Every lot is subjected to comprehensive analytical testing, including HPLC for assay and impurity profiling, to meet precise customer specifications. Certificates of Analysis (COA) documenting identity, purity, and related substances are provided with each 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 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.
