Fmoc-Ser(tBu)-Ser(tBu)-OH (protected Ser-Ser dipeptide) 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. Also
known as Fmoc-serine(tBu)-serine(tBu) dipeptide. The tert-butyl ester
side-chain protection stays intact through chain assembly and is removed in the
final TFA cleavage. ApiSyn provides specifications and COA on request and takes
up custom protected amino acids for non-standard sequences.
