Used as a chiral building block in the synthesis of radiopharmaceuticals, particularly in the development of PET (positron emission tomography) tracers. Its iodo-substituent allows for easy radiolabeling with iodine-123 or iodine-125, making it valuable in neuroimaging studies. The chiral amine moiety enables selective interactions in biological systems, useful in targeting specific receptors or enzymes in the brain. Commonly employed in research for central nervous system disorders, including Parkinson’s and Alzheimer’s diseases.
