Used as a key intermediate in organic synthesis, particularly in the preparation of amino acids and peptides. It serves as a protected glycine equivalent, allowing selective introduction of the glycine moiety in multi-step syntheses. The benzyloxycarbonyl (Cbz) group provides amine protection, while the ester functionalities enable controlled ester hydrolysis or transesterification. Commonly employed in the synthesis of pharmaceuticals, agrochemicals, and biologically active compounds where precise construction of amino acid frameworks is required. Its stability under various reaction conditions makes it suitable for use in convergent synthetic routes.
