1-Octen-3-ol, octenol for short (also known as mushroom alcohol[1]), is a chemical that attracts biting insects such as mosquitos. It is contained in human breath and sweat, and it was once believed that insect repellent DEET works by blocking the insects' octenol odorant receptors.[2][3] Octenol is used in combination with carbon dioxide to attract insects in order to kill them with certain electronic devices.[4]
1-Octen-3-ol is a secondary alcohol derived from 1-octene. It exists in the form of two enantiomers, (R)-(-)-1-octen-3-ol and (S)-(+)-1-octen-3-ol.
Octenol is produced by several plants and fungi, including edible mushrooms. Its odor has been described as green and moldy or meaty; it is used in certain perfumes[citation needed]. It is approved by the U.S. Food and Drug Administration as a food additive.[5] It is of low toxicity with an LD 50 of 340 mg/kg.[4]
