Tans-2-Hexenal is a colorless to pale yellow clear liquid. It occurs naturally in tomatoes, banana and black tea. It gives a leafy, fruity, fatty, apple banana, strawberry note.1 It is mostly used as a flavoring agent in food. It is also used in air care products, cleaning and furnishing care products, laundry and dishwashing products.
(E)-2-Hexenal is the simplest
straight-chain unsaturated aldehyde of interest for perfumes and flavors. It occurs
in essential oils obtained from green leaves of many plants.
(E)-2-Hexenal is a colorless, sharp, herbal-green-smelling liquid with a slight
acrolein-like pungency. Upon dilution, however, it smells pleasantly green and
apple-like. The aldehyde can be synthesized by reacting butanal with vinyl ethyl
ether in the presence of boron trifluoride, followed by hydrolysis of the reaction
product with dilute sulfuric acid.
Biosynthetic methods for its production as natural flavor material have been
developed.
(E)-2-Hexenal has an intense odor and is used in perfumes to obtain a green-leaf
note and in fruit flavors for green nuances.
clear colorless to light yellow liquid
trans-2-Hexen-1-al was used in evaluation of quality of protected designation of origin virgin olive oils by headspace solid-phase microextraction-gas chromatography using flame ionization detection and multivariate analysis. It was used in the multicomponent method for the determination of low-molecular-weight carbonyl compounds in biological samples.
Also known as “leaf aldehyde,” it is of special interest
because it is naturally present in numerous fruits and is
also used as a food additive for flavoring. Feron et al.
identified hexenal in about 80 different types of food.

ChEBI: A 2-hexenal in which the olefinic double bond has E configuration. It occurs naturally in a wide range of fruits, vegetables, and spices.
trans-2-Hexen-1-al is an important flavoring compound that occurs naturally in tomatoes, banana and black tea.
trans-2-HEXENAL is synthesized by the following methods:
1) by reduction of Hexenoic acid with Formic acid vapors over Manganese dioxide at 350℃. 2) by oxidation of the corresponding Hexenol. 3) by condensation of Acetaldehyde with n-Butyraldehyde.
