Quality Control

Every batch of our 2(1H)-Pyrimidinone, 4-Amino-5-Mercapto- (9Ci) undergoes rigorous analytical testing to ensure high purity and consistent quality. Our quality management system is designed to meet the stringent requirements of pharmaceutical-grade intermediates. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with each shipment.

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, the container should be kept under an inert atmosphere (e.g., nitrogen or argon) to prevent oxidation and moisture absorption. Keep away from incompatible materials.
