This chemical is primarily used in peptide synthesis as a coupling reagent. It facilitates the formation of peptide bonds by activating carboxyl groups, making it easier for amino acids to link together. The compound is particularly valuable in solid-phase peptide synthesis (SPPS), where it ensures high efficiency and selectivity in the coupling process. Its structure, which includes a benzyloxycarbonyl (Cbz) protecting group, helps prevent unwanted side reactions during synthesis. Additionally, it is employed in the preparation of complex peptides and proteins for research purposes, including drug development and biochemical studies. Its stability and reactivity make it a preferred choice in organic and medicinal chemistry laboratories.
