O-tert.Butyl-L-threonine tert.butyl ester acetate is a protected, esterified L-threonine derivative in which the threonine side-chain hydroxyl is converted to an O-tert-butyl ether and the carboxyl group is masked as a tert-butyl ester, with an acetate counterion/form remaining as indicated by the product name. The molecule therefore contains a free amino functionality alongside a tert-butyl-protected side-chain oxygen and a tert-butyl ester carbonyl, while the acetate component provides an additional ionic/acid-base form that can affect handling and salt/solvate behavior. This amino acid ester/ether intermediate is used in peptide-related synthesis and chemical labeling workflows where stepwise chemoselective deprotection and controlled reactivity of the amino and carboxyl termini are required.
