Figure 1. Basic Information on Trans-2-Hexenal
Hexenal, an organic compound with the formula C6H10O, includes isomers like trans-2-hexenal and cis-3-hexenal, also known as Aoba-Aldehydes. It has a molecular weight of 98.14 g/mol.
The isomers, notably trans-2-hexenal and cis-3-hexenal, contribute to grass and leaf fragrances, serving as flavoring agents. Although both have plant aromas, trans-2-hexenal is preferred for its aromatic quality over the unpleasant odor of cis-3-hexenal.
Trans-2-hexenal, a colorless to yellow liquid, melts at -39.8°C, boils at 146°C, and has a flash point of 43°C. It dissolves in acetone and ethanol but is nearly insoluble in water. Cis-3-hexenal boils at 126°C.
Figure 2. Basic Information on Cis-3-Hexenal
As aliphatic aldehydes, trans-2-hexenal and cis-3-hexenal have densities of 0.846 g/mL and 0.851 g/mL at 25°C, respectively. Cis-3-hexenal can isomerize to trans-2-hexenal, with its alcohol form, cis-3-hexen-1-ol, being a stable and commonly used fragrance.
The identity of tree fragrance during the fresh green season was first explored by Reinke around 1870 through essential oils. Theodor Curtius identified 2-hexenal in 1912, which Akinawa Hatanaka in 1960 confirmed as the same as the Aoba aldehyde from tea.
Trans-2-hexenal is found in various vegetables and fruits, making up the stink bug odor. Cis-3-hexenal, prevalent in many plants and used as a pheromone by insects, contributes to the aroma of tomatoes and other produce.
Figure 3. Synthesis of Hexenal
Trans-2-hexenal and cis-3-hexenal are synthesized from ethyl vinyl ether and 3-hexen-1-ol, respectively, with cis-3-hexenal also biosynthesized from linolenic acid.
