This compound is a protected glutamic acid derivative, specifically a Cbz- and tert-butyl ester-protected amino acid used as a building block in peptide synthesis. It features benzyloxycarbonyl (Cbz) protection on the amino group and tert-butyl ester protection on both carboxyl groups, enabling selective deprotection during solid-phase or solution-phase peptide assembly.
