Used primarily as an intermediate in the synthesis of pharmaceuticals, particularly in the development of antipsychotic and antidepressant drugs. Its structure supports the creation of active compounds that interact with central nervous system receptors. It is also employed in research settings to design new bioactive molecules, especially those targeting neurological pathways. Due to its nitro group and piperazine ring, it serves as a building block in medicinal chemistry for modifying drug potency and selectivity.
