Azido-PEG-Acid
Azido-PEG-Acid is a heterobifunctional PEG reagent, also known as an azide-terminated PEG, combining an azide group 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. Azido-PEG-Acid reagents are widely used in peptide modification, surface functionalization, and biomaterial development.
