trans,trans-2,4-Hexadienal (sorbic aldehyde) was used in the synthesis of chiral cycloadducts. | [Uses]
2,4-Hexadienal, is used in the synthesis of chiral cycloadducts. 2,4-Hexadienal is used as a flavouring agent, as a chemical intermediate in various organic synthetic reactions and as a raw material in the manufacture of sorbic acid. It is also used as in the manufacture of polymethine dyes, as a pharmaceutical intermediate in the manufacture of mitomycins and antihypercholesteraemics, as an inhibitor of corrosion for steel used in oil field operations, as a monomer in reactions with silane comonomers for the manufacture of polyalkenyloxysilane polymer and as a fumigant against larvae of the Caribbean fruit fly. | [Definition]
ChEBI: (E,E)-2,4-hexadienal is a hexadienal that is hexanal with trans double bonds at positions 2 and 4. It is found in tomatoes, kiwi fruit, mangoes, potato chips, herbs and spices. It has a role as a flavouring agent and a plant metabolite. It is a polyunsaturated fatty aldehyde, a hexadienal and a volatile organic compound. | [Preparation]
Can be obtained by slowly heating crotonaldehyde with acetaldehyde in the presence of pyridine at 85 to 90°C. | [Aroma threshold values]
Detection: 60 to 476 ppb | [Taste threshold values]
Taste characteristics at 25 ppm: sweet, green, waxy, aldehydic, with fresh melon nuances. | [General Description]
trans,trans-2,4-Hexadienal is a volatile is a flavor compound that is reported to occur in different types of tea. |
