Chloro-PEG3-azide is a heterobifunctional linker bearing a reactive chloride for the alkylation of various nucleophilic groups. Due to anchimeric assistance from oxygen, this atom is more reactive than in normal alkyl chlorides. The other reactive group is azide. It can be conjugated via Click chemistry, or reduced to amine group to be later acylated with reactive carbonyl compounds. PEG3 is a versatile hydrophilic linker for bioconjugation.
