Description and Uses
m-PEG12-azide is a aqueous soluble monodisperse PEG linker. The azide group can react with alkyne, BCN, DBCO via Click Chemistry.
PEG functionalized with azide is commonly used in copper-mediated ligation (click chemistry). PEG of this molecular weight should remain amorphous at room temperature.
