Azido-PEG4-4-nitrophenyl carbonate

Azido-PEG4-4-nitrophenyl carbonate contains an azide group and an reactive nitrophenyl carbonate. The nitrophenyl carbonate group can be used to conjugate with amine bearing molecules to form a stable carbamate linkages. The azide reacts with alkyne through Click Chemistry to form stable triazole linkage. The hydrophilic PEG spacer can increase solubility of the resulting molecule in aqueous media.
