Used primarily as an intermediate in organic synthesis, particularly in the production of pharmaceuticals and agrochemicals. Its reactivity allows for the introduction of phenyl and ester functionalities into more complex molecules. Commonly employed in the preparation of α-aryl carbonyl compounds through hydrolysis or reduction reactions. Also serves as a building block in the synthesis of certain anticonvulsant agents and other bioactive molecules due to the presence of the dichloroester group, which can be further modified. Its stability and ease of handling make it suitable for use in multi-step synthetic routes.
