Azido-PEG4-4-nitrophenyl carbonate

Description

Azido-PEG4-4-nitrophenyl carbonate is a PEG linker containing an azide group and an reactive nitrophenyl carbonate(NPC group). The NPC group is reactive towards the amino group of lysine by means of stable urethane linkages. The azide group enables Click Chemistry. The hydrophilic PEG spacer increases solubility in aqueous media.
