1-Octen-3-one, also called octenol, is a volatile organic compound (VOC) present in the atmosphere and various biological sources. It appears as a colorless liquid with a distinctive smell. Octenol is found in plant volatiles and is detectable in the exhaled breath of several animals, including humans. It serves multiple purposes, including its use as an insect attractant, and an indicator for the presence of specific organisms. In scientific research, 1-Octen-3-one is extensively employed. It entices insects, such as mosquitoes and fruit flies, for scientific investigation. Additionally, it aids in identifying the existence of certain organisms like bacteria and fungi.
