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. |
