Alkyne-PEG4-NH2, also known as Alkyne-PEG4-amine, is a PEG derivative with an alkyne functional group (-C≡C) and an amino group (-NH2). The alkyne group enables selective conjugation reactions via copper-catalyzed azide-alkyne cycloaddition (CuAAC) or strain-promoted azide-alkyne cycloaddition (SPAAC) reactions, commonly known as click chemistry. These reactions facilitate the attachment of Alkyne-PEG4-NH2 to molecules, surfaces, or nanoparticles bearing azide groups, allowing for precise control over bioconjugation reactions. ​

The amino group provides versatility for further chemical modification. It can react with activated carboxylic acid groups or other reactive functional groups to form stable amide bonds or other types of linkages, enabling the attachment of Alkyne-PEG4-NH2 to a wide range of molecules or surfaces. ​
