Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of antidiabetic agents such as DPP-4 inhibitors. Its structure allows for selective modification in peptide-like molecules, making it valuable in medicinal chemistry for building complex organic molecules with biological activity. Commonly employed in solid-phase and solution-phase peptide synthesis due to the presence of the Boc (tert-butoxycarbonyl) protecting group, which enables controlled stepwise reactions. Also utilized in research settings for creating analogs and derivatives in drug discovery programs.
