Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of radiolabeled drugs and imaging agents due to the presence of iodine. The Boc-protected amine group allows for selective deprotection and further coupling reactions in peptide synthesis or heterocycle formation. Commonly employed in medicinal chemistry for constructing complex molecules where controlled reactivity and functional group compatibility are required. Also utilized in the preparation of tyrosine analogs for studying enzyme mechanisms or receptor binding.
