Quality Control

Our (E)-3-Hepten-2-One is produced under stringent quality management systems. Each batch undergoes comprehensive analytical testing, including GC, IR, and NMR, to ensure high purity and consistent organoleptic properties. A detailed Certificate of Analysis (COA) is provided with every shipment, confirming compliance with agreed specifications and industry standards for flavor and fragrance ingredients.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from strong bases and incompatible organic solvents. Due to its highly volatile nature, keep containers tightly sealed when not in use. Recommended storage temperature is 2-8°C for extended stability, though short-term storage at 15-25°C is acceptable.
