N3-PEG-N3, MW:1000

N3-PEG-N3 (MW:1000) is a click chemistry reagent. It contains azide groups that can participate in copper-catalyzed azide-alkyne cycloaddition reactions (CuAAc) with alkyne-containing molecules. Additionally, it can engage in strain-promoted azide-alkyne cycloaddition reactions (SPAAC) with molecules containing DBCO or BCN groups.
