Quality Control

Every batch of our 2,4(1H,3H)-Pyrimidinedione,5-Fluorodihydro-6-Methoxy-,cis-(9Ci) is manufactured and tested under a strict quality management system. We provide comprehensive analytical data to ensure the product meets the high-purity standards required for research and synthesis applications. A Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is available for each lot upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place 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. Keep away from incompatible materials such as strong alkalis and fluorides.
