(S)-2-((tert-Butoxycarbonyl)amino)decanoic acid is primarily used in peptide synthesis as a building block for creating specific peptide sequences. Its Boc (tert-butoxycarbonyl) group serves as a protective group for the amino functionality, preventing unwanted reactions during the synthesis process. This compound is particularly valuable in the production of peptides with defined stereochemistry, as the (S)-configuration ensures the correct spatial arrangement of the molecule. It is also employed in the development of bioactive peptides and peptidomimetics, which are used in drug discovery and therapeutic applications. Additionally, it finds utility in research involving amino acid derivatives and their role in studying protein interactions and enzymatic processes.
