Used as an intermediate in organic synthesis, particularly in the production of pharmaceuticals and agrochemicals. Its keto-ester functionality allows it to participate in condensation and cyclization reactions, making it valuable for constructing heterocyclic compounds. Commonly employed in the synthesis of active pharmaceutical ingredients (APIs) where branched-chain esters and ketones are required. Also utilized in fragrance and flavor synthesis due to its reactive carbonyl group, enabling the formation of complex esters and alcohols through reduction or nucleophilic addition.
