Quality Control

Our Calcium [(2,3-Dihydro-1,5-Dimethyl-3-Oxo-2-Phenyl-1H-Pyrazol-4-Yl)Methylamino]Methanesulphonate is manufactured under strict quality systems. Each batch undergoes rigorous analytical testing to ensure identity, purity, and consistency, meeting the stringent requirements for pharmaceutical intermediate applications. Certificates of Analysis (COA) with detailed HPLC, NMR, and elemental analysis data are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place 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.
