Used in the synthesis of peptide-based pharmaceuticals, particularly in developing enzyme inhibitors and receptor agonists/antagonists. Its ether-containing side chain enhances solubility and can improve metabolic stability in drug candidates. Commonly employed in medicinal chemistry for modifying peptide backbone properties, influencing conformation, bioavailability, and target binding affinity. Also utilized in the design of novel antibiotics and neuroactive compounds due to its structural similarity to natural amino acids with modified pharmacokinetic profiles.
