Used primarily as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of active pharmaceutical ingredients (APIs) with central nervous system activity. Its structure allows for selective derivatization, making it valuable in creating compounds with antipsychotic, antidepressant, or anxiolytic properties. Commonly employed in research settings for the preparation of novel receptor ligands, especially targeting serotonin and dopamine receptors. Also utilized in the production of agrochemicals and bioactive molecules where halogenated aromatic amines enhance binding affinity or metabolic stability. Its hydrochloride salt form improves crystallinity and handling during synthetic processes.
