Quality Control

Our 3-Ethenyl-5-Fluoropyridine is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC, GC, NMR, and mass spectrometry, to ensure identity, purity, and consistency. We provide a detailed Certificate of Analysis (COA) with every shipment, confirming compliance with agreed specifications. Our quality commitment supports applications requiring high-purity intermediates for regulatory filings.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at room temperature (15-25°C). Keep away from incompatible materials such as strong bases and oxidizing agents. Due to its fluoride/strong alkali reactivity profile, ensure containers are kept tightly sealed and stored separately from bases.
