Sign in to saveAlso known as (2EZ)-2-Butenal, (2EZ)-But-2-enal
Crotonaldehyde is a chemical compound with the formula CH3CH=CHCHO. The compound is usually sold as a mixture of the E- and Z-isomers, which differ with respect to the relative position of the methyl and formyl groups. The E-isomer is more common. This lachrymatory liquid is moderately soluble in water and miscible in organic solvents. As an unsaturated aldehyde, crotonaldehyde is a versatile intermediate in organic synthesis. It occurs in a variety of foodstuffs, e.g. soybean oils.

==Production and reactivity== Crotonaldehyde is produced by the aldol condensation of acetaldehyde: 2 CH3CHO → CH3CH=CHCHO + H2O
