Propargyl-PEG-Amine

Propargyl-PEG-Amine is a heterobifunctional PEG reagent, also known as Alkyne-functional PEG-amine, combining a terminal alkyne for click chemistry conjugation and a primary amine for covalent attachment to carboxyl groups or other reactive sites. The amine enables direct amidation or further functionalization, while the alkyne allows efficient cycloaddition with azides. Propargyl-PEG-Amine reagents are widely used in bioconjugation, polymer synthesis, and nanomaterial functionalization.
