Used as an intermediate in organic synthesis, particularly in the preparation of pharmaceuticals and fine chemicals. Its keto-ester functionality allows for versatile transformations, such as reduction, alkylation, and cyclization reactions. Commonly employed in the synthesis of heterocyclic compounds and bioactive molecules, including gamma-aminobutyric acid (GABA) analogs and other neurologically active agents. Also utilized in fragrance and flavor synthesis due to its ability to form cyclic ketones and lactones. Suitable for use in research settings for building complex molecular frameworks.
