Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the production of active pharmaceutical ingredients (APIs) with biological activity. Its structure allows for functionalization at multiple sites, making it valuable in constructing complex organic molecules. Commonly employed in reactions involving enolate chemistry or nucleophilic substitution to build cyclic or heterocyclic systems. Also utilized in the development of agrochemicals due to its reactivity and ability to introduce cyclopropyl motifs into target molecules. Its keto-ester functionality enables condensation and cyclization reactions, useful in creating drug-like scaffolds in medicinal chemistry research.
