Used in pharmaceutical research as a synthetic intermediate for developing bioactive peptides and lipid-conjugated compounds. Its structure supports studies on cell permeability and metabolic stability due to the lipophilic acyl chain and amino acid backbone. Commonly employed in the design of enzyme inhibitors or signaling molecules, particularly in immunology and dermatology-related research. Also utilized in formulation development where enhanced membrane absorption is required. The trifluoroacetate salt form improves solubility and handling in aqueous and organic solvent systems.
