Propargyl-PEG2-amine is a PEG derivative containing a propargyl group and an amino group. The amino group is reactive with carboxylic acids, activated NHS esters, carbonyls (ketone, aldehyde) etc. 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. PEG Linkers are useful in the development of antibody drug conjugates (ADCs).
