Z-L-threonine benzyl ester is a protected amino acid ester derived from L-threonine, featuring a threonine side chain with a β-hydroxyl group and an amino acid backbone converted to a benzyl ester at the carboxyl terminus. The "Z" designation indicates a carbamate-type protection on the amino group (commonly benzyl oxycarbonyl, Z), so the molecule bears a protected nitrogen and an esterified carboxyl while retaining the side-chain hydroxyl functionality. This compound is used in peptide and amino acid derivative synthesis as a stepwise building block where the protected amino and esterified carboxyl groups support controlled coupling and subsequent deprotection to access threonine-containing peptide intermediates.
