This compound is primarily used in peptide synthesis as a protecting group for amino acids. The Boc (tert-butoxycarbonyl) group safeguards the amine functionality during the synthesis process, preventing unwanted reactions. The DCHA (dicyclohexylamine) salt form enhances solubility and stability, making it easier to handle and store. It is particularly useful in solid-phase peptide synthesis (SPPS) and solution-phase peptide synthesis, where selective deprotection of the Boc group can be achieved under mild acidic conditions. This allows for the sequential assembly of peptides with high precision and efficiency. Additionally, it is employed in the preparation of complex peptides and proteins for pharmaceutical research, enabling the development of therapeutic agents and biochemical tools.
