3-Isobutyl-2-methoxypyrazine (2-isobutyl-3-methoxypyrazine) is a methoxypyrazine that is very similar to isopropyl methoxy pyrazine except that the alkyl side-group contains an isobutyl group attached to the carbon alpha to the methoxy sidegroup instead of an isopropyl side-group at that same carbon position.
