Used in peptide synthesis as a protected amino acid derivative, it helps in the controlled assembly of peptide chains by preventing unwanted reactions at the amino group. The Boc (tert-butoxycarbonyl) group provides stability during synthesis and can be easily removed under mild acidic conditions. The nitro group on the phenyl ring can serve as a reactive handle for further chemical modifications, making it valuable in the development of bioactive peptides and pharmaceuticals. It is also utilized in research for studying enzyme-substrate interactions and designing enzyme inhibitors.
