[Ser4(tBu)]-Cetrorelix incorporates a tert-butyl-protected serine at position four, modifying steric bulk and local hydrogen-bonding capacity. The protected residue alters polarity and retention properties during purification. Researchers examine its behavior as a synthetic intermediate and structural analog. Applications include SPPS optimization, analog comparison, and protecting-group evaluation.
CAT No: R2726
