Widely used in peptide synthesis as a protected intermediate, this compound enables selective amino group modification while preventing unwanted side reactions. Its benzyloxycarbonyl (Cbz) protecting group allows for mild deprotection under hydrogenation or acidic conditions, making it ideal for stepwise assembly of complex peptides. It is also employed in the preparation of active pharmaceutical ingredients (APIs), particularly in the development of anti-inflammatory and central nervous system agents. The acetic acid moiety provides a handle for further derivatization, enabling linkage to other molecular fragments in drug design. Commonly found in solid-phase synthesis and used in research laboratories for constructing biologically active molecules.
