Used as an intermediate in organic synthesis, particularly in the production of pharmaceuticals and agrochemicals. It serves as an alkylating agent due to the presence of the chloro group, enabling the introduction of ethoxyacetate functionalities into target molecules. Commonly employed in the preparation of beta-keto esters and other carbonyl-containing compounds through condensation reactions. Its reactivity makes it valuable in constructing complex molecular frameworks in medicinal chemistry. Handling requires caution due to its lachrymatory and corrosive properties.
