This is a chiral synthetic intermediate featuring N^α-(1-ethoxycarbonyl-3-phenylpropyl)-L-lysine with an N^ε-trifluoroacetyl protecting group. It is primarily used in peptide synthesis, peptidomimetic design, and pharmaceutical research as a building block for complex molecules. The structure enables incorporation into larger peptide sequences or mimics, supporting the development of enzyme inhibitors and receptor modulators for diseases such as cancer and metabolic disorders. The trifluoroacetamido group serves as a protecting group for the lysine side chain, aiding in selective synthesis, improving solubility, and enhancing stability during handling and optimization.
