Z-L-Alanine N-carboxyanhydride

Z-L-Alanine N-carboxyanhydride is a protected amino acid N-carboxyanhydride derived from L-alanine, featuring a cyclic carboxyanhydride (NCA) ring that serves as an activated alanine building block. The molecule bears a benzyloxycarbonyl (Z, Cbz) protecting group on the amino functionality, while retaining the alanine side chain and providing a reactive NCA carbonyl system for controlled ring-opening polymerization chemistry. Z-L-Alanine N-carboxyanhydride is used in peptide and polypeptide synthesis contexts, where its activated NCA structure enables stepwise incorporation of alanine residues into growing chains under conditions that promote nucleophilic ring opening.
