Quality Control

Our 4-Methyl-1,3-Pentadiene is produced and handled under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including gas chromatography (GC) for purity and identity confirmation, to ensure it meets the stringent requirements of our industrial and research partners. A detailed Certificate of Analysis (COA) is provided with every shipment, guaranteeing traceability and compliance with agreed specifications.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) in a cool, well-ventilated place, away from heat, sparks, and open flames. Due to its highly volatile and easily oxidized nature, the container must be kept tightly sealed and should be used promptly after opening. Recommended storage temperature is 2-8°C.
