This compound is primarily used in peptide synthesis as a protected amino acid derivative. It serves as a building block for constructing complex peptides and proteins, particularly in research and pharmaceutical development. The tert-butoxycarbonyl (Boc) group acts as a protective moiety for the amino group, preventing unwanted reactions during peptide chain assembly. Its quinolin-3-yl side chain introduces specific structural and functional properties, making it valuable in designing peptides with targeted biological activities. It is often employed in the development of drug candidates, enzyme inhibitors, and bioactive molecules, particularly those targeting diseases like cancer or infections due to the quinoline moiety's pharmacological relevance. Additionally, it is utilized in solid-phase peptide synthesis (SPPS) for efficient and controlled peptide production.
