Used primarily in pharmaceutical research as an intermediate in the synthesis of biologically active compounds, particularly those targeting the central nervous system. It serves as a key building block for developing receptor agonists and antagonists, especially in studies related to neurological disorders. Its structure supports the development of molecules with high selectivity for neurotransmitter receptors, making it valuable in drug discovery for conditions such as anxiety, depression, and cognitive impairments. Additionally, it is employed in the preparation of radiolabeled derivatives for use in receptor binding assays and imaging studies.
