Quality Control

Our 5-Amino-3-mercapto-[1,2,4]triazolo-[4,3-a]pyrimidin-7-ol is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation via IR and NMR spectroscopy, to ensure it meets the high standards required for research and synthesis. A comprehensive Certificate of Analysis (COA) detailing all specifications is provided with every shipment to guarantee traceability, consistency, and reliability for your critical processes.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at a controlled room temperature (15-25°C). Due to its sensitivity to oxidation, prolonged storage under an inert atmosphere (e.g., nitrogen or argon) is recommended for optimal long-term stability. Keep away from strong oxidizing agents.
