Quality Control

Our 4 5-Diamino-6-Hydroxy-2-Mercaptopyrimidine is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure identity, purity, and consistency, meeting the high standards required for research and industrial synthesis. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). Due to its hygroscopic and easily oxidized nature, the container should be kept sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent moisture uptake and degradation.
