Quality Control

Our 2,5,6-Triaminopyrimidine-4(3H)-Thione is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing to ensure identity, purity, and consistency. We provide comprehensive Certificates of Analysis (COA) with key parameters including assay (HPLC), related substances, residual solvents, and loss on drying. Our quality commitment supports applications requiring high-purity intermediates, including cGMP-compliant pharmaceutical synthesis.

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.
