Propargyl-PEG6-NH2(CAT: I014635) is a heterobifunctional polyethylene glycol (PEG) linker designed for advanced chemical and biochemical conjugation. It features a propargyl (alkyne) group at one end, enabling copper-catalyzed azide–alkyne cycloaddition (“click chemistry”), and a primary amine group at the other, which reacts readily with activated esters (e.g., NHS esters), carboxylic acids, or aldehydes. The PEG6 spacer provides flexibility, water solubility, and reduced steric hindrance, making it especially useful for bioconjugation, drug delivery, surface functionalization, and labeling of biomolecules. Propargyl-PEG6-NH2 is widely applied in chemical biology, materials science, and biomedical research where precise, stable, and versatile linkages are required.
