Cas no 721385-17-7 (4-Ethyl-D-phenylalanine)

4-Ethyl-D-phenylalanine is a non-natural amino acid derivative characterized by the presence of an ethyl group at the para position of the phenyl ring in the D-configuration. This structural modification enhances its steric and electronic properties, making it a valuable chiral building block in pharmaceutical synthesis and peptide research. Its distinct side-chain substitution improves metabolic stability and binding affinity in bioactive compounds, particularly in the development of enzyme inhibitors and receptor modulators. The D-configuration offers resistance to proteolytic degradation, expanding its utility in designing peptidomimetics and therapeutic agents. High purity and well-defined stereochemistry ensure reproducibility in research and industrial applications.
