Alkyne-PEG8-NH2 (Propargyl-PEG8-Amine, CAS 1196732-52-1) is a bifunctional PEG linker featuring a terminal propargyl (alkyne) group and a primary amine group, separated by an eight-unit ethylene glycol (PEG8) spacer. This structure combines the high reactivity of the alkyne group for copper-catalyzed azide-alkyne cycloaddition (CuAAC) reactions with the versatility of the amine group for forming stable amide bonds with carboxyl groups or activated esters.
