Used as a chiral building block in the synthesis of pharmaceuticals, particularly in the development of central nervous system agents and radiopharmaceuticals. Its iodine substituent allows for easy radiolabeling with iodine-123 or iodine-131, making it valuable in imaging and therapeutic applications, especially in neuroscience research and the study of neurotransmitter receptors. The amine group enables coupling to various functional moieties, enhancing its utility in medicinal chemistry for creating targeted compounds.
