2-Decanone

2-Decanone is a ketone with the chemical formula C₁₀ H₂₀ O.

Occurrence

2-Decanone can be found in meats, dairy products and eggs, fruits, vegetables, and grains such as maize, rice, and oats. It also is present in fish, some nuts, honey, ginger, garlic, vanilla, hop oil, mate, brandy, tea, and coffee. It is found in the highest concentrations in milk and hop oil. 2-Decanone was also found at varying percentages in the essential oils of plants within the Ruta genus, including R. montana and R. chalepensis. Within the stem bark of Commiphora rostrata, 2-decanone was found at 69%.

2-Decanone has been found to possess strong fumigant activity against the maize weevil. However, it is less repellent towards the maize weevil than other alkanones.

2-Decanone can be synthesized by reacting 2-decanol with permanganic acid and copper sulfate in DCM.
