Infobox references

Heptanal or heptanaldehyde is an alkyl aldehyde. It is a colourless liquid with a strong fruity odor, which is used as precursor to components in perfumes and lubricants.^[2]

Production

It can be obtained from castor oil by distillation under reduced pressure.^[1] It is synthesized by degradation of the esters of ricinoleic acid. It is also prepared by hydroformylation of hexene.^[2]

Uses

Industrially, it is used in the manufacture of α-amylcinnamaldehyde, a component of many fragrances.^[2] It is the precursor to 1-heptanol and ethyl heptanoate, the latter being a component of certain lubricants.^[3]
