N3-PEG2-OH (CAS NO.: 139115-90-5) is a PEG linker featuring an azide group and a terminal hydroxyl group. The azide group is compatible with Click Chemistry, reacting with alkyne, DBCO, or BCN groups to form stable triazole linkages, while the hydroxyl group allows for further functionalization or modification with other reactive groups.

This compound serves as a PEG-based PROTAC linker and a versatile reagent in Click Chemistry applications. It supports copper-catalyzed azide-alkyne cycloaddition (CuAAC) with alkyne-containing molecules and strain-promoted alkyne-azide cycloaddition (SPAAC) with DBCO or BCN-containing molecules, making it ideal for drug discovery, bioconjugation, and advanced material synthesis.
