Mal-PEG4-bis-PEG4-propargyl

Mal-PEG4-bis-PEG4-propargyl, an 8-unit PEG ADC linker, facilitates the synthesis of antibody-drug conjugates (ADCs) [1]. This compound also serves as a click chemistry reagent featuring an Alkyne group, which enables copper-catalyzed azide-alkyne cycloaddition (CuAAc) with Azide-bearing molecules.
