Description and Uses

2,4-Heptadienal retards or prevents the development of "off-flavors" in auto-oxidizing fats and oils. May be prepared by reduction with LiAlH4 of the dienoic acid prepared by the Doebner synthesis, followed by oxidation with Mn02 of the resulting dienol to the corresponding dienol; by the method of Marshall and Whiting.

trans,trans-2,4-Heptanedienal is an unsaturated aldehyde that has a fishy odour. trans,trans-2,4-Heptanedienal is a volatile component naturally found in drinking water and fish oils.
