This compound is widely used in peptide synthesis as a protected form of tyrosine. It serves as a building block in the production of complex peptides, ensuring the tyrosine residue remains intact during the reaction process. The Boc (tert-butoxycarbonyl) group protects the amino group, while the O-methyl group protects the phenolic hydroxyl of the tyrosine side chain, with the carboxyl group remaining free to allow selective deprotection and coupling in multi-step peptide synthesis. It is particularly valuable in pharmaceutical research for creating peptide-based drugs, where precise control over amino acid incorporation is essential. Additionally, it is employed in biochemical studies to investigate protein structure and function by incorporating modified tyrosine residues into peptides.
