Z-DL-Asp-OH

Z-DL-Asp-OH is a protected amino acid derivative of aspartic acid featuring a benzyloxycarbonyl (Z, Cbz) protecting group on the amino functionality and a free carboxylic acid at the side chain and α-position, with the "DL" designation indicating a racemic mixture of stereoisomers. The molecule contains both amine-protected and carboxyl groups, and the aspartyl side chain bears a terminal carboxyl group that can participate in salt formation, hydrogen bonding, and acid-base equilibria during peptide coupling or analytical workflows. Z-DL-Asp-OH is used as a building block in peptide synthesis and related amino acid derivative preparation, where the Z group supports chemoselective handling of the amino functionality while the carboxyl groups provide defined sites for further functionalization or incorporation into peptide intermediates.
