This chemical is primarily used in peptide synthesis as a protected amino acid derivative. It serves as a building block for creating complex peptides, ensuring the tyrosine residue remains unaffected during the reaction process. Its application is crucial in pharmaceutical research, particularly in developing peptide-based drugs and therapeutic agents. The Boc (tert-butoxycarbonyl) group provides stability, while the Bzl (benzyl) group protects the hydroxyl function of tyrosine, allowing selective deprotection and modification in subsequent steps. This compound is especially valuable in solid-phase peptide synthesis, enabling the production of high-purity peptides for biological studies and drug development.
