Azido-PEG9-CH2COOH

Azido-PEG9-CH2COOH is a PROTAC linker of the PEG category utilized in synthesizing PROTAC molecules. This compound functions as a click chemistry reagent, featuring an Azide group that can undergo copper-catalyzed azide-alkyne cycloaddition reactions (CuAAC) with molecules containing an Alkyne group. Additionally, it can participate in strain-promoted azide-alkyne cycloaddition reactions (SPAAC) with molecules that have DBCO or BCN groups.
