Verwenden
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.
synthetische
Can be obtained by slowly heating crotonaldehyde with acetaldehyde in the presence of pyridine at 85 to 90°C.
