Quality Control

Our 2(1H)-Pyrimidinone, 4-Hydroxy-5-Methyl- (9Ci) is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing to ensure high purity and consistency, meeting the stringent requirements for pharmaceutical and fine chemical intermediates. Certificates of Analysis (COA) detailing purity, identity, and impurity profiles are available for every shipment upon request.

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 (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent degradation from atmospheric moisture.
