Used primarily in peptide synthesis, this compound serves as a protective group for hydroxyproline during the formation of peptide chains. It is particularly valuable in solid-phase peptide synthesis (SPPS) where it helps in the stepwise assembly of peptides. The Fmoc group provides temporary protection for the amino group, while the Bzl group protects the hydroxyl group of hydroxyproline, ensuring that these functional groups do not react prematurely. This allows for precise control over the sequence and structure of the synthesized peptide, which is crucial in the development of pharmaceuticals, bioactive peptides, and research tools. After the peptide chain is assembled, the protective groups can be removed under specific conditions to yield the desired peptide.
