Quality Control

Our production of 2-(3,5-Dimethyl-1-Phenyl-1H-Pyrazol-4-Yl)-3-Hydroxy-2,3-Dihydroquinazolin-4(1H)-One adheres to stringent quality management protocols. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation via spectroscopic methods, to ensure consistency and compliance with research-grade specifications. Certificates of Analysis (COA) detailing batch-specific results are available upon request to support your quality assurance and regulatory documentation needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (typically 15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed after opening to minimize exposure to atmospheric moisture. For long-term storage, consider the use of desiccants.
