Used as a key intermediate in the synthesis of agrochemicals and pharmaceuticals, particularly in the production of pyrethroid insecticides. It serves as a building block for introducing the dimethylcyanoacetyl moiety, which enhances the stability and bioactivity of final compounds. Also employed in the preparation of heterocyclic compounds due to its reactive nitrile and ketone functional groups. Its compact, branched structure makes it valuable in fine chemical synthesis where steric effects influence reactivity and selectivity.
