Z-N-Me-Thr-OH · CHA is a protected, N-methylated derivative of threonine featuring a Z (benzyloxycarbonyl/Cbz-type) carbamate on the amino functionality and a free carboxylic acid, with the threonine side chain bearing a β-hydroxyl group. The molecule contains an N-methyl substituent that modifies the amide/carbamate nitrogen and can influence hydrogen-bonding and coupling behavior, while the Z-protecting group masks the primary amino group to reduce undesired side reactions during peptide assembly; stereochemistry is not specified in the provided name. In synthesis and chemical biology workflows, this protected amino acid is used as a stepwise building block or intermediate for preparing threonine-containing peptide derivatives and for generating labeled or structurally defined amino acid analogues where controlled protection and side-chain functionality are required.
