Z-4-phenyl-Phe-OH

Z-4-phenyl-Phe-OH is a protected amino acid derivative belonging to the phenylalanine (Phe) family, featuring a benzyl-protecting group on the amino terminus and a 4-phenyl-substituted phenylalanine side chain. The molecule contains a free carboxylic acid (-COOH) and a protected amino group (Z, i.e., benzyloxycarbonyl/CBZ-type carbamate), with the aromatic side-chain functionality providing hydrophobic character and π-interactions relevant to peptide building blocks. Z-4-phenyl-Phe-OH is used in peptide synthesis workflows and related structure-activity or labeling studies where a controlled, protected amino acid with an extended aromatic side chain is incorporated as a defined intermediate.

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