This compound is primarily used in peptide synthesis as a protected amino acid derivative. It serves as a building block for constructing peptides, particularly in solid-phase peptide synthesis (SPPS). The Boc (tert-butoxycarbonyl) groups protect the lysine side chain and the amine group, preventing unwanted reactions during peptide chain assembly. This allows for precise control over the sequence and structure of the peptide being synthesized. It is especially useful in the production of complex peptides for research, pharmaceuticals, and biotechnology applications, where specific amino acid sequences are critical for biological activity. After the peptide synthesis is complete, the Boc groups can be removed under acidic conditions to yield the desired peptide.
