Description

Fmoc-Cys(Et)-OH is a bench-stable, moisture-tolerant cysteine derivative featuring a trifluoroethyl side chain. This protected amino acid integrates seamlessly into solid-phase peptide synthesis workflows, enabling site-specific incorporation of thiol-containing residues with minimal oxidation risk. The Fmoc group ensures efficient deprotection under mild basic conditions, while the ethyl substituent enhances solubility and reduces aggregation during chain elongation.
