Quality Control

Our Pyrimido[4,5-D]Pyrimidin-2-Ol, 5,6-Dihydro- (6Ci) is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation via spectroscopic methods, to ensure it meets the high standards required for research and synthesis. Certificates of Analysis (COA) detailing all specifications are available upon request to support your quality assurance and regulatory 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 (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent degradation from atmospheric moisture.
