Azido-PEG9-alcohol

Azido-PEG9-alcohol is a click chemistry crosslinker with an azide group and a terminal hydroxyl group. The hydrophilic PEG spacer increases solubility in aqueous media. The azide group can react with alkyne such as , BCN, DBCO via Click Chemistry to yield a stable triazole linkage. The hydroxyl group enables further derivatization or replacement with other reactive functional groups.
