γ-Aminobutyric acid t-butyl ester HCl is a protected amino acid ester derivative of γ-aminobutyric acid, featuring a four-carbon (γ-amino) backbone with an esterified carboxyl group masked as a tert-butyl ester and present as the hydrochloride salt. The molecule contains a free primary amino group (as its protonated chloride salt form) and a tert-butyl ester that can be removed under acidic conditions to regenerate the corresponding γ-carboxylic acid while retaining the amino functionality for further coupling. In peptide and amide synthesis workflows, it functions as a protected GABA building block that supports stepwise assembly and chemoselective handling of the amino and carboxyl functionalities during preparation of γ-aminobutyric acid-containing intermediates and labeled or conjugated derivatives.
