Used primarily in peptide synthesis, particularly in solid-phase peptide synthesis (SPPS), where it serves as a protecting group for the amino group of proline. It ensures selective deprotection during the synthesis process, enabling the stepwise construction of peptides. Commonly employed in the production of pharmaceuticals, bioactive peptides, and research compounds. Its stability and compatibility with various reagents make it a valuable tool in organic and medicinal chemistry for designing complex peptide structures.
