Description
N-(Amino-PEG2)-N-bis(PEG3-azide) is a branched reagent designed for click chemistry, featuring two azides (N3) and an amine group. The azide can react with alkynes, BCN, or DBCO through click chemistry to form stable triazole linkages. The amine is reactive towards activated NHS esters or carboxylic acids in the presence of HATU or EDC.
