Quality Control

Our 1-Pentene-3-Yne is produced and handled under stringent quality management protocols. Each batch undergoes comprehensive analytical testing, including Gas Chromatography (GC) and spectroscopic methods, to ensure identity, purity, and consistency. 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. Store under an inert atmosphere (e.g., nitrogen or argon) in a cool, well-ventilated area, away from heat, sparks, and open flames. Due to its highly volatile and easily oxidized nature, containers must be kept tightly sealed and should be used promptly after opening. Recommended storage temperature is 2-8°C for extended stability.
