Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the production of antidepressant and antipsychotic drugs. Its structure allows for the introduction of cyclopropane and nitrile functionalities, which are valuable in modifying drug potency and metabolic stability. Also employed in agrochemical research for developing new herbicides and insecticides due to its halogenated aromatic backbone, which enhances bioactivity. Commonly utilized in medicinal chemistry for structure-activity relationship (SAR) studies involving CNS-targeted compounds.
