Also known as isobutanal, alpha-methylpropionaldehyde, isobutyric aldehyde, isobutylaldehyde, 2-methylpropionaldehyde, 2-methylpropanal, isobutyl aldehyde, iso-butyraldehyde

Isobutyraldehyde is the chemical compound with the formula (CH3)2CHCHO. It is an aldehyde, isomeric with n-butyraldehyde (butanal). Isobutyraldehyde is made, often as a side-product, by the hydroformylation of propene. Its odour is described as that of wet cereal or straw. It undergoes the Cannizzaro reaction even though it has alpha hydrogen atom. It is a colorless volatile liquid.
