Used primarily in peptide synthesis as a protected amino acid derivative, this compound enables the controlled assembly of complex peptides by preventing unwanted side reactions. The fluorenylmethyloxycarbonyl (Fmoc) group provides temporary protection to the amino functionality, allowing selective deprotection under mild basic conditions, which is compatible with a wide range of side-chain protecting groups. Its cyclopropane ring introduces structural rigidity, making it valuable in the design of conformationally constrained peptides for pharmaceutical and biochemical research. The sodium salt form enhances solubility in polar solvents, facilitating its use in solid-phase and solution-phase synthesis. It is especially useful in the development of bioactive peptides, enzyme inhibitors, and peptidomimetics.
