Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of active pharmaceutical ingredients (APIs) targeting central nervous system disorders. Its structure allows for the introduction of piperazine-based moieties, which are common in drugs with antipsychotic, antidepressant, or antihistaminic activity. It is also employed in the preparation of kinase inhibitors and other bioactive molecules in medicinal chemistry research. Due to its amine and chloro functional groups, it serves as a versatile building block for cross-coupling reactions and nucleophilic substitutions in drug discovery pathways.
