Used as a key intermediate in organic synthesis, particularly in the preparation of pharmaceuticals and agrochemicals. Its ketoester functionality allows for versatile reactivity, including enolate formation and nucleophilic addition, making it valuable in constructing complex molecules. Commonly employed in the synthesis of heterocyclic compounds and as a building block in the production of active ingredients in crop protection agents. Also utilized in the development of specialty polymers and fine chemicals due to its ability to undergo selective transformations.
