Description and Uses

cis-4-Heptenal has an odor reminiscent of heptaldehyde. It is suggestive of fried fats on dilution. It is used to impart a fried, buttery flavor. It is prepared from Hemiptera insects (trans-form); from pen-ten-l-en-3-ol converted to the corresponding vinyl ether which undergoes a Claisen rearrangement to 4-heptenal (transform).

cis-4-Heptenal is an unsaturated aldehyde that possesses a fishy aroma. cis-4-Heptenal is a product of oxidative breakdown of fats in fish, and is naturally found in fish oils.
