Used primarily in peptide synthesis, it serves as a protecting group for amino acids, ensuring specific reactions occur without unwanted side effects. It is particularly valuable in solid-phase peptide synthesis (SPPS), where it helps build complex peptides step-by-step. Its application extends to the development of pharmaceuticals, enabling the creation of peptide-based drugs with precise structures. Additionally, it is utilized in biochemical research to study protein interactions and functions, aiding in the understanding of biological processes. Its stability and ease of removal make it a preferred choice in synthetic chemistry for constructing peptide chains efficiently.
