This compound is primarily used in peptide synthesis as a protected form of tyrosine. The Boc (tert-butyloxycarbonyl) groups protect the amino and hydroxyl functionalities during the synthesis process, preventing unwanted side reactions. It is particularly valuable in solid-phase peptide synthesis (SPPS) where selective deprotection is required to build complex peptide chains. Additionally, it finds application in the preparation of modified peptides and bioactive molecules, where controlled introduction of tyrosine residues is necessary. Its stability and ease of deprotection make it a preferred choice in research and pharmaceutical development.
