N-(acid-PEG3)-N-bis(PEG3-azide) is a branched PEG derivative containing two terminal azide groups and a terminal carbozylic acid. The azide groups allow for PEGylation via Click Chemistry. In the presence of activators (e.g. EDC, or DCC) the terminal carboxylic acid can be reacted with primary amino groups to form a stable amide bond.
