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), [3] herbs (such as rosemary, [4] basil, and thyme [5] ), and nectarines. [6] It was also found to be present in Japanese catnip (Schizonepeta tenuifolia) [7] and the pine king bolete (Boletus pinophilus).
