Azido-PEG4-(CH2)3-methyl ester is a PEG-based PROTAC linker utilized in the synthesis of PROTACs. It functions as a click chemistry reagent, containing an azide group. This allows it to participate in copper-catalyzed azide-alkyne cycloaddition reactions (CuAAc) with molecules possessing alkyne groups. It can also engage in strain-promoted alkyne-azide cycloaddition (SPAAC) reactions with molecules containing DBCO or BCN groups.
- PEG-based PROTAC linker for PROTAC synthesis.
- Click chemistry reagent.
- Contains an azide group.
- Undergoes copper-catalyzed azide-alkyne cycloaddition reaction (CuAAc) with alkyne groups.
- Undergoes strain-promoted alkyne-azide cycloaddition (SPAAC) reactions with DBCO or BCN groups.
