Used in organic synthesis as a building block for peptides and small molecules, particularly in the preparation of cyclopropyl-containing compounds. It serves as a protective group for amines during chemical reactions, enabling selective modifications. Applied in medicinal chemistry for the development of biologically active compounds, including potential drug candidates. Its cyclopropyl ring structure is valuable in designing molecules with specific conformational properties, often enhancing stability or binding affinity. Also utilized in research for studying enzyme inhibitors and receptor ligands due to its unique structural features.
