Used in the synthesis of radiopharmaceuticals for positron emission tomography (PET) imaging. Its iodine-containing structure allows labeling with radioactive iodine isotopes, enabling visualization of biological targets such as tumors or neurological receptors. The compound serves as a precursor in developing amino acid-based tracers that target amino acid transport systems overexpressed in cancer cells. It is also investigated for use in central nervous system imaging due to its ability to cross the blood-brain barrier.
