Quality Control

Our 2,4(1H,3H)-Pyrimidinedione, 5-Fluoro-, 4-Hydrazone (9Ci) is manufactured under strict quality management systems. Every batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation via spectroscopic methods (NMR, IR, MS), to ensure it meets the high standards required for research and development. Certificates of Analysis (COA) detailing batch-specific results are available upon request to support your quality assurance protocols.

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 sensitivity to fluoride/strong alkali, keep away from incompatible materials. For long-term storage, consider storing under an inert atmosphere to maximize stability.
