Quality Control

Our 5-Benzyl-6-Methyl-2-(5-Oxo-3-Phenyl-2,5-Dihydro-1H-Pyrazol-1-Yl)-4(3H)-Pyrimidinone is manufactured under a strict quality management system. Every batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation via spectroscopic methods (NMR, IR, MS). We provide a detailed Certificate of Analysis (COA) with each shipment, ensuring traceability and compliance with your research or cGMP-grade requirements.

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 nature, the container must be kept tightly sealed after each use to minimize exposure to atmospheric moisture. For long-term storage, consider using desiccants.
