This chemical is primarily used in peptide synthesis as a protected form of threonine. The benzyl (Bzl) groups act as protecting groups for the hydroxyl and carboxyl functionalities, preventing unwanted reactions during peptide bond formation. It is particularly valuable in solid-phase peptide synthesis (SPPS) and solution-phase synthesis, where selective deprotection is required to build complex peptide sequences. The oxalate salt form enhances its stability and solubility, making it easier to handle in organic solvents. It is commonly employed in the production of pharmaceuticals, bioactive peptides, and research applications involving peptide modification and study.
