Used in pharmaceutical research as a key intermediate in the synthesis of bioactive compounds targeting neurological disorders, particularly as a precursor for radiolabeled tracers in dopamine D2 receptor imaging. The iodine substituent enables radiolabeling with ¹²³I for SPECT studies, aiding in the diagnosis and research of conditions like Parkinson's disease and schizophrenia. Its structure facilitates blood-brain barrier penetration, making it valuable in CNS drug design. Not currently used in general clinical settings; primarily for laboratory research.
