| Hazard Information | Back Directory | [Description]
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). | [Chemical Properties]
(Z)-4-Heptenal is a widespread volatile trace constituent
of food flavors. It is a colorless, oily liquidwith a powerful, fatty, somewhat
fishy, and, in high dilution, creamy odor. It can be prepared by several ways, for
example, by starting from (Z)-3-hexenol.
(Z)-4-Heptenal is used in cream, butter, and fat flavors. | [Chemical Properties]

clear colorless to light yellow liquid | [Occurrence]
Reported found as a constitutent in butterfat, microbial fermented tea and black Hemiptera bugs | [Uses]
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. | [Preparation]
From Hemiptera bugs (trans-form); from penten-1-en-3-ol converted to the corresponding vinyl ether, which undergoes a Claisen rearrangement to 4-heptenal (trans-form). | [Aroma threshold values]
Detection: 0.4 ppb. |
