This compound is primarily used in organic synthesis as a reagent for the preparation of peptides and other bioactive molecules. It serves as an activated ester, facilitating the coupling of amino acids or peptides by reacting with amine groups. The benzyloxycarbonyl (Cbz) protecting group ensures selective protection of amino functionalities during synthesis, preventing unwanted side reactions. Its application is significant in the development of pharmaceuticals, particularly in the synthesis of peptide-based drugs, where precise control over molecular structure is crucial. Additionally, it can be employed in the modification of polymers or surfaces to introduce specific functional groups for further chemical reactions.
