Propargyl-PEG-Acid

Propargyl-PEG-Acid is a heterobifunctional PEG reagent, also known as Alkyne-terminated PEG-acid, featuring a terminal alkyne for click chemistry conjugation and a carboxylic acid for covalent attachment to amines. The carboxylic acid can be activated for amide bond formation, enabling versatile bioconjugation strategies. Propargyl-PEG-Acid reagents are widely used in peptide modification, polymer synthesis, and biomaterial development.
