Quality Control

Our cis-1,3-Pentadiene is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including GC, GC-MS, and NMR, to ensure high purity and consistent isomer composition. A detailed Certificate of Analysis (COA) is provided with every shipment, confirming compliance with agreed specifications.

Storage

Preserve in a tightly closed container, protected from light. Due to its highly volatile nature, store in a cool, well-ventilated area away from heat, sparks, and open flames. Recommended storage temperature is 2-8°C under an inert atmosphere (e.g., nitrogen) to minimize polymerization and oxidation risks. Keep away from strong oxidizing agents.
