Quality Control

Our 5,6-Diamino-2,4-Dihydroxypyrimidine Sulfate Dihydrate is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing to ensure identity, purity, and consistency, meeting the stringent requirements for use as a pharmaceutical intermediate. Certificates of Analysis (COA) detailing purity, assay, 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 nature, the container must be kept tightly sealed after opening to prevent moisture absorption, which can affect product stability and performance.
