Primarily used in peptide synthesis as a protecting group for the carboxyl function of aspartic acid. It helps in preventing unwanted side reactions during the coupling of amino acids. The Boc (tert-butyloxycarbonyl) group is stable under basic conditions but can be easily removed under acidic conditions, making it highly useful in solid-phase peptide synthesis. The OcHex (cyclohexyl ester) group provides additional protection and stability, particularly in complex peptide sequences. This compound is essential in the production of peptides for pharmaceutical research, enabling the creation of specific peptide bonds without interference from the aspartic acid side chain. Its application is critical in the development of therapeutic peptides and bioactive molecules.
