Z-Ser(Bzl)-OSu is a protected serine derivative bearing a benzylic side-chain protecting group (Bzl) and a Z (benzyloxycarbonyl) group on the amino functionality, with the carboxyl terminus converted to an N-hydroxysuccinimide (OSu) ester. The molecule contains the serine backbone featuring a primary alcohol side chain masked as a benzyl ether, while the OSu ester retains a reactive carboxyl-derived carbonyl for acyl transfer chemistry and the Z group provides chemoselective control of the amine during peptide coupling workflows. Z-Ser(Bzl)-OSu is used as an activated amino acid intermediate for forming peptide bonds or for preparing amide-linked conjugates in solution-phase or solid-phase synthesis contexts where stepwise coupling and controlled functional-group reactivity are required.
