Z-L-Phenylalanine N-carboxyanhydride

Z-L-Phenylalanine N-carboxyanhydride is a phenylalanine-derived N-carboxyanhydride (NCA) in which the amino acid nitrogen is incorporated into a cyclic anhydride, bearing a Z (benzyloxycarbonyl) protecting group on the nitrogen and a phenyl side chain characteristic of L-phenylalanine. The molecule contains the reactive NCA carbonyl functionality within the anhydride ring alongside the benzyloxycarbonyl (Z) carbamate and the pendant benzyl-substituted phenyl group, with stereochemistry corresponding to the L-phenylalanine precursor as indicated by the product name. It is employed as a peptide-building intermediate in controlled polymerization and solid-phase or solution-phase peptide synthesis workflows, where the NCA ring can undergo ring-opening to generate growing peptide chains with phenylalanine residues under conditions compatible with carbamate-protected termini.

Designed for biological research and industrial applications, not intended for individual clinical or medical purposes.
