Pentanal

Pentanal is the organic compound is an alkyl aldehyde, molecular formula C5H10O. It is used in flavorings, resin chemistry, and rubber accelerators. Its smell is described as fermented, bready, fruity, nutty, berry.

Pentanal is used in diverse flavors (e. g. fruit flavors) and as a vulcanization accelerator.

2-Propyl-2-heptenal is obtained from pentanal by aldol condensation, which is hydrogenated to the saturated branched 2-propylheptanol. This alcohol serves as a starting material for the PVC plasticizer di-2-propylheptyl phthalate (DPHP).

Valeraldehyde is oxidized to give valeric acid.
