This chemical is primarily used in peptide synthesis as a building block. It serves as a protected form of the amino acid ornithine, ensuring specific reactions occur at desired sites during peptide chain assembly. The tert-butoxycarbonyl (Boc) group protects the amine functionality, preventing unwanted side reactions. It is particularly valuable in solid-phase peptide synthesis, where controlled deprotection and coupling steps are essential. Additionally, it finds applications in the development of pharmaceuticals and bioactive peptides, where precise structural control is critical for efficacy. Its role in synthesizing complex peptides makes it a key component in drug discovery and biochemical research.
