Description and Uses
Isobutyronitrile can be derived from isobutyraldehyde. It is used in organic synthesis, as a catalyst in the polymerization of ethylene and in the petroleum industry as a gasoline additive. Isobutyronitrile is also used to synthesize the intermediate 2-isopropyl-4-methyl-6-hydroxypyrimidine of the organophosphorus insecticide diazinon.
