Quality Control

Our 5,6-Dichloropyrimidine-2,4-Diamine is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation, to ensure it meets the high standards required for research and synthesis. A detailed Certificate of Analysis (COA) with batch-specific data is provided with every shipment to guarantee traceability and consistency.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place. Due to its hygroscopic nature, the container should be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) for long-term storage to prevent moisture absorption and degradation. Recommended storage temperature is 2-8°C for prolonged stability.
