Quality Control

Our 2,4-Pyrimidinedicarbonitrile, 5,6-Diamino- is manufactured under strict quality management protocols. Each batch undergoes comprehensive analytical testing to ensure high purity and consistent performance as a critical intermediate. We provide full traceability and a detailed Certificate of Analysis (COA) with every shipment, confirming identity, purity, and impurity profiles. Our quality systems are designed to support GMP and ISO standards for regulated applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at 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. Keep away from incompatible materials.
