Widely used in organic synthesis, particularly as an intermediate in the production of pharmaceuticals and agrochemicals. Its keto-ester functionality allows it to participate in condensation reactions, making it valuable for constructing complex molecules. Commonly employed in the synthesis of heterocyclic compounds and active pharmaceutical ingredients (APIs), especially those requiring gamma-keto ester building blocks. Also utilized in the preparation of flavor and fragrance compounds due to its reactivity and ability to form derivatives with aromatic properties.
