Used as an intermediate in the synthesis of pharmaceuticals and agrochemicals, particularly in the development of active ingredients that require nitroaromatic or ester functionalities. Its chloro and nitro groups allow for further functionalization through nucleophilic substitution or reduction reactions, making it valuable in constructing complex organic molecules. Commonly employed in research settings for preparing heterocyclic compounds and in the optimization of synthetic routes where a protected carboxylic acid group is needed.
