| Hazard Information | Back Directory | [Description]
2-Methyl-2-butenal has a penetrating, powerful green ethereal
odor. May be prepared by condensation of acetaldehyde and propionaldehyde. | [Chemical Properties]
clear colorless to yellow liquid | [Uses]
Tiglic aldehyde was used in the concise total synthesis of 7-demethylpiericidin A1. It was used as starting reagent during the synthesis of:
- alkyl-branched tetraene hydrocarbons, pheromone component for dried fruit beetle
- E,E-2,4-dimethyl-2,4-hexa dienal, volatile constituents of the defensive secretions of Leiobunum nigripalpi
- 4-methyl-2,4-hexadiene-1-ol
| [General Description]
trans-2-Methyl-2-butenal is one of the major volatile constituents of coriander and olive oil. |
