2-((Azido-PEG8-carbamoyl)methoxy)acetic acid is a PEG linker containing an azide group with a terminal carboxylic acid. The azido group can react with alkynes, BCN, DBCO to form stable triazole bonds by Click Chemistry. The terminal carboxylic acid can react with primary amine groups to form stable amide bonds in the presence of activators such as EDC or HATU.

2-((Azido-PEG8-carbamoyl)methoxy)acetic acid is a monodispersed PEG linker, which can act as ADC linkers. It is a PEG-based PROTAC linker that can be used in the synthesis of PROTACs.
