This compound is primarily used in peptide synthesis as a protected form of threonine. The Boc (tert-butoxycarbonyl) group serves as a protective group for the amino functionality, while the Bzl (benzyl) group protects the hydroxyl side chain of threonine. This dual protection is crucial in solid-phase peptide synthesis, allowing selective deprotection and coupling steps to build complex peptide sequences efficiently. It is particularly valuable in the synthesis of therapeutic peptides, where precise control over amino acid incorporation is essential. Additionally, it finds application in research laboratories for developing peptide-based drugs, studying protein interactions, and exploring biochemical pathways. Its stability and compatibility with various coupling reagents make it a reliable choice in organic and medicinal chemistry.
