Used as an intermediate in organic synthesis, particularly in the production of pharmaceuticals and agrochemicals. Its ester and chloro functionalities make it suitable for nucleophilic substitution reactions, enabling the construction of more complex molecules. Commonly employed in the synthesis of active ingredients in herbicides and insecticides due to its ability to introduce alkyl and functionalized side chains. Also utilized in the preparation of specialty monomers for polymer chemistry, where it contributes to modifying polymer backbone structures with tailored properties.
