Threo-DL-Phenyserine is a threonine-derived, non-proteinogenic amino acid bearing a phenyl-substituted side chain and a β-hydroxyl group, classified as a serine/threonine analog with an amino acid backbone. The molecule contains a free amino group and a free carboxyl group along with a hydroxylated side chain, and the "threo-DL" designation indicates a threo relationship between stereocenters with a racemic (DL) stereochemical composition. It is used as a substrate analog and building block in chemical biology and peptide/peptidomimetic synthesis for structure-activity studies, side-chain functionalization, and analytical method development involving serine-like residues.
