Used in peptide synthesis as a protected derivative of N-methylthreonine. It facilitates the controlled incorporation of N-methylthreonine residues into peptide chains. The Boc group protects the amino functionality, while the Bzl (benzyl) group protects the hydroxyl group, preventing unwanted side reactions. This ensures precise and efficient peptide assembly, particularly in solid-phase peptide synthesis. Commonly applied in the production of pharmaceuticals, bioactive peptides, and research compounds.
