Methyltetrazine-PEG4-azide is a PEG derivative containing a methyltetrazine and azide moiety. The azide group can participate in copper-catalyzed Click Chemistry reactions with reagents such as alkynes, DBCO and BCN to form triazole moieties. The hydrophilic PEG linker increases the water solubility of the compound in aqueous media.
