Z-L-Ile-OSu

Z-L-Ile-OSu is a protected amino acid derivative consisting of L-isoleucine bearing a benzyloxycarbonyl (Z, Cbz) protecting group on the amino functionality and an activated N-hydroxysuccinimide (OSu) ester at the carboxylate. The molecule contains a stereogenic center consistent with the L designation, a branched aliphatic side chain characteristic of isoleucine, and it presents an N-hydroxysuccinimide leaving group that enables acyl transfer chemistry while maintaining the Z-protected amine. Z-L-Ile-OSu is used as an amino-acid coupling intermediate in peptide synthesis and in solution-phase derivatization workflows where the OSu ester format supports formation of amide bonds with nucleophiles under controlled conditions.
