Quality Control

Every batch of 3-Ethenyl-1,4-Pentadiene is produced and tested under a strict quality management system. We provide comprehensive analytical data to ensure the product meets the high-purity standards required for sensitive synthetic applications. A detailed Certificate of Analysis (COA) is supplied with each shipment, confirming identity, purity, and impurity profiles as determined by GC, HPLC, and NMR.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). Due to its properties of being easily oxidized, it is recommended to store under an inert atmosphere (e.g., nitrogen or argon) for long-term stability. Keep away from heat, sparks, open flames, and incompatible materials.
