Used in peptide synthesis as a protecting group for the amino group of aspartic acid, ensuring selective reactions during the formation of peptide bonds. It is particularly valuable in solid-phase peptide synthesis (SPPS) to prevent unwanted side reactions. The Boc group can be easily removed under acidic conditions, allowing for controlled deprotection and further modification of the peptide chain. This compound is essential in the production of complex peptides and proteins for research, pharmaceuticals, and biotechnology applications.
