Monodisperse Azido-PEG2-acid (N3-PEG2-COOH) is a PEG linker containing an azide (N3) group with a terminal carboxylic acid (COOH). The hydrophilic PEG spacer increases solubility in aqueous media. The azide group can react with alkyne, BCN, DBCO via Click Chemistry to yield a stable triazole linkage. The terminal carboxylic acid can react with primary amine groups in the presence of activators (e.g. EDC, or HATU) to form a stable amide bond.
