Medchemexpress LLC Biotin-PEG4-Amide-C6-Azide | 1006592-62-6 | 99.1% | C27H49N7O7S | 1 G
Biotin-PEG4-Amide-C6-Azide is a PEG-based PROTAC linker used in the synthesis of PROTACs. This click chemistry reagent contains an azide group, enabling copper-catalyzed azide-alkyne cycloaddition (CuAAc) with alkyne-containing molecules and strain-promoted alkyne-azide cycloaddition (SPAAC) reactions with DBCO or BCN group molecules. PROTACs utilize the ubiquitin-proteasome system for selective protein degradation.
- PEG-based PROTAC linker
- Used in PROTAC synthesis
- Click chemistry reagent with azide group
- Supports copper-catalyzed azide-alkyne cycloaddition (CuAAc)
- Enables strain-promoted alkyne-azide cycloaddition (SPAAC)
- Facilitates selective degradation of target proteins
- For research use only
