trans-2-Pentenal Usage And Synthesis
Chemical PropertiesCLEAR COLORLESS TO YELLOW LIQUID
Uses(E)-2-Pentenal, is a flavor volatile found in tomato, virgin olive oil and sardine.
DefinitionChEBI: (E)-2-pentenal is a 2-pentenal in which the double bond has (E)-configuration. It is found in cigarette smoke, virgin olive oil, and milk. It has a role as a plant metabolite.
General DescriptionTrans-2-Pentenal (pentenal) is an α,β-unsaturated aldehyde that increases [Ca2+] in cultured neonatal rat trigeminal ganglion (TG) neurons. The gas-phase reactions of NO3 radicals with pentenal in pure N2, using a relative rate technique, was studied.
Safety ProfileMutation data reported. When heated to decompositionit emits acrid smoke and irritating vapors.
