Also known as hexyl aldehyde, caproaldehyde, capronaldehyde, hexylaldehyde, hexanaldehyde, caproic aldehyde, hexaldehyde, n-hexylaldehyde

Hexanal, also called hexanaldehyde or caproaldehyde is an alkyl aldehyde used in the flavor industry to produce fruity flavors. Its scent resembles freshly cut grass, like cis-3-hexenal. It is potentially useful as a natural extract that prevents fruit spoilage. It occurs naturally, and contributes to a hay-like "off-note" flavor in green peas.
