Boc-PEG1-PPG2-C2-azido

Boc-PEG1-PPG2-C2-azido is a PROTAC linker of the PEG class, utilized in PROTAC molecule synthesis. This compound acts as a click chemistry reagent containing an azide group, enabling copper-catalyzed azide-alkyne cycloaddition reactions (CuAAc) with alkyne-containing molecules. Additionally, it participates in strain-promoted azide-alkyne cycloaddition reactions (SPAAC) with molecules containing DBCO or BCN groups.
