Quality Control

Our 2,5-Diaminothiazolo(5,4-D)Pyrimidin-7(6H)-One is manufactured under strict quality management protocols to ensure batch-to-batch consistency and high purity for research applications. Each lot is analyzed using advanced chromatographic and spectroscopic techniques, including HPLC and NMR, to confirm identity and purity. A comprehensive Certificate of Analysis (COA) detailing all test results is provided with every shipment 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 area at a controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed after each use to prevent moisture absorption, which may affect stability and performance. Keep away from incompatible materials.
