This chemical is primarily used in peptide synthesis as a protected amino acid derivative. It serves as a building block for constructing peptides, particularly in solid-phase peptide synthesis (SPPS) methods. The tert-butyl (tBu) protecting group ensures selective deprotection during the synthesis process, while the DCHA (dicyclohexylamine) salt form enhances stability and solubility in organic solvents. It is commonly employed in the production of peptides for pharmaceutical research, drug development, and biochemical studies. Its role is critical in ensuring the accurate and efficient assembly of peptide chains, particularly in the synthesis of complex or therapeutic peptides.
