Boc-L-2-aminobutanoic acid（Cat No.:I043090）is a protected form of L-2-aminobutanoic acid, where the amino group is protected with a tert-butoxycarbonyl (Boc) group. This protection prevents unwanted reactions during peptide synthesis, especially in solid-phase peptide synthesis (SPPS). The carboxyl group remains free for coupling with other amino acids, enabling the incorporation of this unique amino acid into peptides. L-2-aminobutanoic acid is often used to introduce branched side chains into peptides, potentially affecting their structure, stability, and biological activity. This compound is useful in peptide design for research and pharmaceutical applications.
