This compound is primarily used in peptide synthesis as a protecting group for tyrosine. The tert-butyl group shields the hydroxyl group of tyrosine, preventing unwanted reactions during the peptide assembly process. Its inclusion of dicyclohexylamine (DCHA) enhances stability and solubility, making it easier to handle in organic solvents. This makes it particularly useful in solid-phase peptide synthesis (SPPS), where selective deprotection is required to build complex peptide chains. It is also employed in the production of custom peptides for research in biochemistry, pharmaceuticals, and drug development, where precise control over peptide structure is critical.
