4,7,10,13,16-Pentaoxanonadeca-1,18-diyne Usage And Synthesis
DescriptionBis-propargyl-PEG5 is a crosslinker containing propargyl groups at both ends. The propargyl groups reacts with azide-bearing compounds or biomolecules via copper catalyzed Click Chemistry to form stable triazole linkages.
UsesBis-propargyl-PEG4 is a PEG-based PROTAC linker used in the synthesis of PROTACs. Bis-propargyl-PEG4 is used for the synthesis of demethylvancomycin dimers[1][2]. Bis-propargyl-PEG4 is a click chemistry reagent, it contains an Alkyne group and can undergo copper-catalyzed azide-alkyne cycloaddition (CuAAc) with molecules containing Azide groups.
