Propargyl-PEG2-t-butyl ester Usage And Synthesis
DescriptionPropargyl-PEG2-t-butyl ester is a PEG linker that enables Click Chemistry reactions with azide-bearing compounds or biomolecules; copper will be required for catalyzation. Under acidic conditions, the t-butyl group can be removed.
UsesPropargyl-PEG2-Boc is a PEG-based PROTAC linker that can be used in the synthesis of PROTACs[1]. Propargyl-PEG2-Boc is a click chemistry reagent, it contains an Alkyne group and can undergo copper-catalyzed azide-alkyne cycloaddition (CuAAc) with molecules containing Azide groups.
