Quality Control

Our 4,5-Diaminopyrimidine is manufactured under a strict quality management system to ensure batch-to-batch consistency and high purity. Each lot is subjected to comprehensive analytical testing, including HPLC for assay and related substances, IR for identification, and KF for moisture content. A detailed Certificate of Analysis (COA) is provided with every shipment, confirming compliance with agreed specifications. We support cGMP and ISO 9001 standards for pharmaceutical and industrial applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, 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 purity and stability. Keep away from incompatible materials such as strong oxidizing agents.
