[Description]

Propargyl-PEG3-CH2CO2H is an PEG linker with an alkyne and carboxylic acid set of functional groups. The alkyne group can participate in copper catalyzed azide-alkyne Click Chemistry to form stable triazole linkage. The carboxylic acid can react with primary amines to form stable amide bonds; activator (e.g. EDC, or HATU) is needed.
