N,N-Bis(PEG2-alkyne)-N-amido-PEG2-thiol

N,N-Bis(PEG2-alkyne)-N-amido-PEG2-thiol is an ADC linker that integrates four PEG units and is used in creating antibody-drug conjugates (ADCs) [1]. This compound functions as a click chemistry reagent possessing an Alkyne group, which enables it to participate in copper-catalyzed azide-alkyne cycloaddition (CuAAc) with molecules that contain Azide groups.
