Boc-L-aspartic acid α-amide is widely used in peptide synthesis as a protected form of aspartic acid. The Boc (tert-butyloxycarbonyl) group serves as a temporary protecting group for the amino group, allowing selective reactions at other sites of the molecule during peptide chain assembly. This compound is particularly valuable in solid-phase peptide synthesis (SPPS), where it ensures precise control over the sequence and structure of the peptide being synthesized. It is also employed in the preparation of aspartic acid-containing peptides for research in biochemistry and pharmaceuticals, including the development of enzyme inhibitors, therapeutic peptides, and bioactive compounds. Its stability and ease of deprotection make it a preferred choice in complex peptide synthesis workflows.
