Quality Control

Our 4(3H)-Pyrimidinone, 2-Mercapto- (9Ci) is produced under a strict quality management system. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation (IR, NMR), to ensure it meets the high standards required for research and development. A comprehensive Certificate of Analysis (COA) detailing all test results is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) in a cool, dry place at room temperature (15-25°C). Due to its sensitivity to oxidation, minimize headspace in opened containers and handle under appropriate conditions to preserve stability.
