Propargyl-PEG4-thiol

Propargyl-PEG4-thiol is a PEG-based PROTAC linker can be used in the synthesis of PROTACs. Propargyl-PEG4-thiol is a non-cleavable ADC linker used in the synthesis of antibody-drug conjugates (ADCs) [1]. Propargyl-PEG4-thiol is a click chemistry reagent, it contains an Alkyne group and can undergo copper-catalyzed azide-alkyne cycloaddition (CuAAc) with molecules containing Azide groups.
