Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of central nervous system agents. Shows utility in creating potent modulators of neurotransmitter receptors due to its ability to cross the blood-brain barrier. Employed in research for novel antidepressants and antipsychotics. Also applied in agrochemical research for developing new classes of pesticides with selective activity. Its bifunctional chloro groups allow for sequential coupling reactions, making it valuable in medicinal chemistry for building complex heterocyclic systems.
