H-Asp(OtBu)-OH (CAS: 3057-74-7) is a protected form of L-aspartic acid, in which the β-carboxyl side chain is masked with a tert-butyl (OtBu) group. This protection is essential in peptide synthesis, especially in solid-phase peptide synthesis (SPPS), to avoid undesired side reactions and to ensure selectivity during coupling steps. Since aspartic acid contains two carboxylic acid groups (α and β), selective protection of the side chain is critical for precise peptide construction. It is widely used in the development of pharmaceutical peptides, biomaterials, vaccines, and other bioactive compounds.
