Fmoc-PEG-Acetic Acid
Fmoc-PEG-Acetic Acid is a heterobifunctional reagent designed for solid-phase peptide synthesis (SPPS), providing temporary Fmoc protection for the amine group while enabling carboxyl-mediated conjugation during peptide assembly. Its key advantages include orthogonal reactivity for sequential modifications, tunable spacer length (n), and enhanced solubility for hydrophobic peptide segments, though the Fmoc group requires alkaline deprotection and the carboxyl group may need activation for amidation.
