 | Hazard Information | Back Directory |  | [Description] 
 Propargyl-PEG4-CH2CO2tBu is a PEG reagent that can reacts with azide compounds or biomolecules under the catalyzation of copper. The t-butyl protected carboxyl group can be deprotected under acidic conditions.
 |  | [Uses] 
 Propargyl-PEG3-OCH2-Boc is a PEG-based PROTAC linker that can be used in the synthesis of PROTACs[1]. Propargyl-PEG3-OCH2-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.
