Bromoacetamido-PEG2-azide linker contains a bromide group and a terminal azide. The azide group can react with alkyne, BCN, DBCO via Click Chemistry to form a stable triazole linkage. The bromoacetamide is widely used as thiol labelling and thiol capping reagent. It undergoes a fast nucleophilic substitution reaction with thiol. The PEG spacer can increase the solubility of compounds in aqueous media.
