Hexanal

Chemical compound / From Wikipedia, the free encyclopedia

Hexanal, also called hexanaldehyde or caproaldehyde is an alkyl aldehyde used in the flavor industry to produce fruity flavors.[4] Its scent resembles freshly cut grass, like cis-3-hexenal.[5] It is potentially useful as a natural extract that prevents fruit spoilage.[6] It occurs naturally, and contributes to a hay-like "off-note" flavor in green peas.[7]
