This compound, known as Boc-Gly-Leu-OH, is a protected dipeptide utilized primarily in solid-phase peptide synthesis as a building block for constructing complex peptide sequences. The Boc (tert-butoxycarbonyl) group protects the N-terminal amino group of the glycine residue, enabling selective deprotection and subsequent coupling reactions while preventing unwanted side reactions at reactive sites. This facilitates the precise assembly of peptides in both research and industrial applications. It is also employed in the synthesis of pharmaceutical intermediates, contributing to the development of bioactive peptides and therapeutic agents by enhancing synthetic control, though the protecting groups are typically removed in the final product.
