Alkyne-PEG5-OH, also known as Propargyl-PEG5-alcohol, is a type of PEG derivative featuring a propargyl (alkyne) functional group at one end and a hydroxyl group at the other end. The hydroxyl group enables further derivatization or replacement with other reactive functional groups. The propargyl group can be reacted with azide-bearing compounds or biomolecules via copper catalyzed azide-alkyne Click Chemistry to yield a stable triazole linkage.
