Used as an intermediate in the synthesis of pharmaceuticals, particularly in the preparation of anticoagulant and anti-inflammatory agents. It serves as a building block in organic reactions where the ester and keto functionalities allow for further chemical modifications. Commonly employed in the formation of heterocyclic compounds through cyclization reactions. Also utilized in the development of agrochemicals and dyes due to its reactive α-keto ester structure. Its chlorophenyl group enhances reactivity in cross-coupling reactions, making it valuable in medicinal chemistry research.
