Quality Control

Our 3-Methyl-4-Penten-2-One is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including Gas Chromatography (GC) and spectroscopic methods, to ensure high 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 in a cool, well-ventilated area away from heat, sparks, and open flame. Due to its highly volatile and easily oxidized nature, it is recommended to store under an inert atmosphere (e.g., nitrogen) for long-term stability. Keep container tightly sealed when not in use to prevent evaporation and contamination.
