Used primarily in research settings as a peptide building block, this compound supports the synthesis of larger peptide structures with modified amino acid residues. Its methylated amino groups enhance metabolic stability and resistance to enzymatic degradation, making it valuable in developing bioactive peptides with improved pharmacokinetic profiles. It is also employed in structure-activity relationship (SAR) studies to assess the effect of N-methylation on peptide conformation, receptor binding, and biological activity. Due to its amide and amino functionalities, it participates in solid-phase peptide synthesis and solution-phase coupling reactions. Its hydrochloride salt form improves solubility and handling in aqueous environments.
