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. |
