This compound is primarily utilized in peptide synthesis as a protected form of tyrosine, where the Boc (tert-butyloxycarbonyl) group safeguards the amino functionality during the synthesis process. The N-methylation of tyrosine enhances the peptide's stability and resistance to enzymatic degradation, making it valuable in the development of bioactive peptides and pharmaceuticals. The DCHA (dicyclohexylamine) salt form improves solubility and handling, facilitating its use in solid-phase peptide synthesis (SPPS) and other organic reactions. It is particularly useful in creating peptide-based drugs, hormone analogs, and research tools for studying peptide interactions and functions in biological systems.
