Fmoc-Gly-Ala-Phe-OtBu is a protected peptide fragment used
in convergent (fragment-condensation) peptide synthesis, which can improve
coupling efficiency and reduce racemisation and deletion risk at difficult
junctions compared with stepwise assembly. The tert-butyl ester side-chain
protection stays intact through chain assembly and is removed in the final TFA
cleavage. ApiSyn supplies it from Ahmedabad, India, for peptide R&D and
process development.
