Quality Control

Our production of Ammonium 4-[4-[3-[4-(Dimethylamino)Phenyl]-2-Propenylidene]-4,5-Dihydro-3-Methyl-5-Oxo-1H-Pyrazol-1-Yl]Benzenesulphonate adheres to a stringent quality management system. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation via IR and NMR spectroscopy, to ensure it meets precise customer specifications and consistent batch-to-batch performance. Certificates of Analysis (COA) documenting all critical parameters are provided with every shipment.

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 tightly sealed after opening to prevent degradation from atmospheric moisture. Keep away from incompatible materials.
