3-Octanone is an organic compound with the formula C5H11C(O)C2H5. A colorless fragrant liquid, it is classified as a ketone. It is one of three octanones, the others being 2-octanone and 4-octanone.
3-Octanone is found in a variety of sources such as plants (such as lavender), herbs (such as rosemary, basil, and thyme), and nectarines. It was also found to be present in Japanese catnip (Schizonepeta tenuifolia) and the pine king bolete (Boletus pinophilus). It is produced by oyster mushrooms as an nematicide to kill roundworms.
