Used primarily as a key intermediate in organic synthesis, particularly in the production of pharmaceuticals and agrochemicals. Its reactive keto-ester functionality allows for facile modification, enabling the construction of complex molecules. Commonly employed in the synthesis of active pharmaceutical ingredients (APIs) where it serves as a building block for heterocyclic compounds. Also utilized in the preparation of flavor and fragrance compounds due to its ability to form ester and carbonyl derivatives with distinct sensory profiles. Its structural features make it valuable in condensation reactions and in the development of novel synthetic pathways requiring selective carbon-chain elongation or cyclization.
