Z-D-Leu-OSu

Z-D-Leu-OSu contains the amino acid side chain of D-leucine linked to a benzyloxycarbonyl (Z, Cbz) protected amino group and an N-hydroxysuccinimide ester (OSu) at the carboxylate, forming a peptide-coupling-ready derivative rather than a free amino acid. The molecule bears a secondary amide-forming functionality via the OSu ester, while the Z protecting group masks the α-amino group to control chemoselectivity during acylation chemistry, and the D stereochemistry is specified by the name. Z-D-Leu-OSu is used in synthesis and chemical biology workflows where activated amino acid esters support stepwise peptide bond formation or enable conjugation strategies that require an amino acid-derived acylating handle under controlled conditions.

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