Z-Tyr-OHex is a protected tyrosine amino acid derivative in which the α-amino group is masked with a benzyloxycarbonyl (Z, Cbz) protecting group and the α-carboxyl group is esterified as a hexyl ester (OHex), forming a non-free amino acid suitable for peptide chemistry. The aromatic phenolic side chain of the tyrosine residue remains present as a functional hydroxyl group, while the molecule contains the protected amino functionality and the esterified carboxyl group that together control chemoselectivity during coupling steps. Z-Tyr-OHex is used as a building block in peptide synthesis and related derivatization workflows where protected amino and ester forms help manage reactivity, and it can serve as a precursor to tyrosine-containing peptide intermediates or conjugation targets after appropriate deprotection and functional group handling.
