Quality Control

Our 4-Hexen-3-One is produced under stringent quality management systems. Every batch undergoes comprehensive analytical testing, including GC, HPLC, and NMR, to ensure high purity and consistent performance. A detailed Certificate of Analysis (COA) is provided with each shipment, confirming compliance with agreed specifications. We support compliance with global regulatory frameworks, including REACH.

Storage

Preserve in a tightly closed container, protected from light. Due to its highly volatile and easily oxidized nature, store under an inert atmosphere (e.g., nitrogen) in a cool, well-ventilated place. Recommended storage temperature is 2-8°C to maximize stability. Keep away from heat, sparks, and open flames.
