Chemical Properties

Colorless liquid

Uses

trans-2-Octenal is one of the probable major contributors to the Californian long-grain cooked rice odor.

Definition

ChEBI: The (E)-isomer of oct-2-enal.

Synthesis Reference(s)

The Journal of Organic Chemistry, 51, p. 2607, 1986 DOI: 10.1021/jo00363a043
Journal of the American Chemical Society, 93, p. 1724, 1971 DOI: 10.1021/ja00736a027
Tetrahedron, 39, p. 3207, 1983 DOI: 10.1016/S0040-4020(01)91568-6

General Description

The rate constant for the gas-phase reaction of the NO(3) radical with trans-2-octenal was studied using absolute rate method. The fungal volatile organic compound trans-2-octenal, caused locomotory defects and changes in green fluorescent protein (GFP) and antigen-labeled dopaminergic neurons in adult Drosophila melanogaster.

Safety Profile

Mutation data reported. Whenheated to decomposition it emits acrid smoke andirritating vapors.
