Used as an intermediate in the synthesis of pharmaceuticals, particularly in the development of anticoagulant and anti-inflammatory agents. It serves as a building block for heterocyclic compounds due to the presence of both ester and keto functionalities adjacent to the aromatic ring. Its reactivity allows for nucleophilic substitution and condensation reactions, making it valuable in the preparation of more complex molecules in medicinal chemistry. Also employed in the production of agrochemicals and dyes where chlorinated aromatic esters are required.
