Crotonaldehyde is a chemical compound with the formula CH3CH=CHCHO. The compound exists as two isomers, E- and Z- depending on the relative position of the methyl (CH3) and formyl (CHO) groups. The E-isomer is more common (data given in Table is for the E-isomer). 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.
