Boc-3-iodo-L-phenylalanine (CAS 273221-75-3)

Boc-3-iodo-L-phenylalanine is a specialized derivative of phenylalanine, distinguished by the incorporation of an iodine atom at the 3-position of the benzyl side chain and protected by a tert-butoxycarbonyl (Boc) group on the amino function. This compound is of particular interest in the realm of peptide chemistry and molecular biology research, serving as a pivotal building block for the synthesis of peptides and proteins with specific structural and functional properties. The presence of the iodine atom introduces unique physicochemical characteristics, such as enhanced molecular weight and altered electronic properties, making it useful for studying protein interactions, folding, and stability. Additionally, the Boc group provides a protective mechanism, ensuring the amino group remains inert during certain reactions, thereby allowing for the sequential construction of peptides without undesired side reactions. In research, Boc-3-iodo-L-phenylalanine is utilized not only for its role in the synthesis of novel peptides but also for its application in radiochemical studies, where the iodine atom can be exploited for radiolabeling, enabling the tracking and imaging of peptides and proteins in complex biological systems. This compound exemplifies the sophisticated chemical engineering strategies employed to explore and manipulate biological processes at the molecular level, offering insights into protein structure, function, and dynamics.
