Used in pharmaceutical research as an intermediate for synthesizing central nervous system agents, particularly in the development of antidepressants and anticonvulsants. Shows activity as a GABA uptake inhibitor, making it valuable in studying neurological disorders like epilepsy and anxiety. Also employed in the preparation of bioactive molecules due to its ability to cross the blood-brain barrier. Commonly used in structure-activity relationship (SAR) studies for optimizing drug candidates targeting neurotransmitter transporters.
