Quality Control

Our Potassium 4-[4-[[4-(Dimethylamino)Phenyl]Methylene]-4,5-Dihydro-3-Methyl-5-Oxo-1H-Pyrazol-1-Yl]Benzenesulphonate is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing, including HPLC, NMR, and elemental analysis, to ensure identity, purity, and consistency. Certificates of Analysis (COA) detailing all specifications are provided and can be tailored to meet specific customer or regulatory requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, 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.
