PEG3-(Amino-Tri-(Propargyl-PEG2-ethoxymethyl)-methane)-(Amino-Tri-(carboxyethoxymethyl)-methane) is reactive with azide-bearing compounds or biomolecules via copper catalyzed azide-alkyne Click Chemistry to yield a stable triazole linkage. The terminal carboxylic acid groups can react with primary amino groups in the presence of activators (e.g. HATU) to form a stable amide bond.

t-Boc-N-amido-Tri-(propargyl-PEG10-ethoxymethyl)-methane is reactive with azide-bearing compounds or biomolecules via copper catalyzed azide-alkyne Click Chemistry to yield a stable triazole linkage. The Boc group can be deprotected under mild acidic conditions to form the free amine. Reagent grade, for research use only.
