What is 2-(2-Azidoethoxy)ethanol?
Description
Azido-PEG2-alcohol is a PEG linker containing an azide group and a terminal hydroxyl group. 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 hydroxyl group enables further derivatization or replacement with other reactive functional groups.
