Used primarily in peptide synthesis, this compound serves as a building block for creating modified peptides with specific biological activities. Its incorporation into peptide chains can enhance binding affinity to target receptors, making it valuable in drug development, particularly for designing therapeutic agents targeting neurological disorders or metabolic diseases. The chlorine substitutions on the phenyl ring improve stability and interaction with hydrophobic regions of proteins, making it useful in research focused on enzyme inhibition or receptor modulation. Additionally, it is employed in the study of structure-activity relationships to optimize peptide-based drugs for improved efficacy and selectivity.
