Quality Control

Our (1,2,4)Triazolo(1,5-A)Pyrimidin-7(1H)-One, 2-(Chloromethyl)-5-Methyl- is manufactured under a strict quality management system. Every batch undergoes comprehensive analytical testing, including HPLC for purity, NMR and IR for structural confirmation, and residual solvent analysis, to ensure it meets the high standards required for research and synthesis. Certificates of Analysis (COA) detailing all specifications are provided with each shipment and are available upon request.

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 (moisture-sensitive) nature, the container must be kept tightly sealed after each use to prevent degradation from atmospheric moisture. Keep away from incompatible materials.
