| | TRANS-2-NONENAL Usage And Synthesis |
| Chemical Properties | CLEAR COLOURLESS TO PALE YELLOW LIQUID | | Uses | trans-2-Nonenal is an unsaturated aldehyde that is a product of fatty acid peroxidation (and also has a grassy, cucumber smell). trans-2-Nonenal is naturally found in mushrooms, coffee and is also a constituent of carrot root. It also exhibits insecticidal effects. | | Definition | ChEBI: (E)-non-2-enal is a monounsaturated fatty aldehyde that is (2E)-non-2-ene which is carrying an oxo group at position 1. It has a role as a plant metabolite. It is a monounsaturated fatty aldehyde, an enal and a medium-chain fatty aldehyde. | | Synthesis Reference(s) | Tetrahedron Letters, 24, p. 4829, 1983 DOI: 10.1016/S0040-4039(00)94018-8 | | General Description | trans-2-Nonenal (T2N) is a volatile unsaturated aldehyde with an unpleasant greasy odor, present in low concentrations in barley, malt, and certain vegetables. It is utilized as an insect repellent, insecticide, and flavor compound. T2N is one of the basic components contributing to the off-flavor and odor in stored beer. |
