m-PEG5-azide is a PEG-based PROTAC linker utilized in the synthesis of PROTACs. This click chemistry reagent incorporates an azide group, enabling its participation in copper-catalyzed azide-alkyne cycloaddition (CuAAC) with molecules containing alkyne groups. It can also engage in strain-promoted alkyne-azide cycloaddition (SPAAC) reactions with compounds featuring DBCO or BCN groups. This compound is intended for research use only and has not been validated for medical applications. Recommended storage is at -20°C, sealed, and away from moisture.
- Used in the synthesis of PROTACs
- Features an azide group for click chemistry
- Participates in CuAAC reactions with alkyne-containing molecules
- Can undergo SPAAC reactions with DBCO or BCN groups
- Research use only
