Fmoc-NH-PEG11-CH2CH2COOH(CAT: I045961) is a heterobifunctional polyethylene glycol (PEG) linker featuring an Fmoc-protected amine on one terminus and a carboxylic acid group on the other, separated by an 11-unit PEG chain plus an ethylene spacer. The Fmoc group allows controlled deprotection under mild basic conditions, enabling sequential synthetic steps in solid-phase peptide synthesis (SPPS) or bioconjugation. The terminal carboxylic acid can be activated for coupling with amines, forming stable amide bonds. The PEG11 spacer imparts hydrophilicity, flexibility, and solubility while minimizing steric hindrance. This reagent is widely applied in peptide synthesis, drug delivery, bioconjugation, and materials research requiring long, functional PEG linkers.
