Used as a building block in peptide synthesis, particularly for creating specific peptide sequences in pharmaceutical research. It serves as a protected form of proline, ensuring controlled reactions during peptide chain assembly. Commonly applied in the development of drugs targeting neurological disorders, cardiovascular diseases, and metabolic conditions. Its stability and reactivity make it suitable for solid-phase peptide synthesis, enabling the production of complex peptides with high precision. Also utilized in biochemical studies to investigate protein folding and enzyme interactions.
