Isobutyraldehyde is used as an intermediate in the preparation of isobutanol, methacrolein, hydroxypivaldehyde and neopentyl glycol. It is actively involved in the Cannizaro reaction. It is also used as an intermediate to prepare pharmaceuticals, agrochemicals, vitamins, antioxidants, rubber accelerators, textile auxiliaries, perfumery and flavors.
