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[edit]

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[edit]

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]
