Azido-PEG4-oxazolidin-2-one is a bifunctional crosslinker containing an azide group and an oxazolidin group. The Oxazolidin-2-onegroup is an efficient ligand for the copper catalyst and used for an improved copper catalyzed click chemistry. The azide group can react with alkyne, BCN, DBCO via Click Chemistry to afford a stable triazole linkage. The PEG spacer increases the aqueous solubility of the resulting compound.
