Quality Control

Our 1-(4-Chlorophenyl)-1H-Pyrazolo[3,4-D]Pyrimidin-4-Ol is manufactured under strict quality management systems. Every batch undergoes rigorous analytical testing, including HPLC, NMR, and MS, to ensure identity, purity, and consistency. Certificates of Analysis (COA) detailing all specifications are provided with each shipment to support your quality assurance and regulatory requirements.

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 each use to prevent degradation from atmospheric moisture.
