Azido-PEG9-acid is a PEG molecule consisting of an azide and a terminal carboxylic acid. The hydrophilic PEG spacer increases solubility in aqueous media. The azide group can react with alkyne, BCN, DBCO via Click Chemistry to yield a stable triazole linkage. The terminal carboxylic acid can react with primary amine groups in the presence of activators (e.g. EDC, or HATU). | [Uses]
Azido-PEG9-acid is a non-cleavable 9 unit PEG ADC linker used in the synthesis of antibody-drug conjugates (ADCs). Azido-PEG9-acid is a PEG-based PROTAC linker can be used in the synthesis of PROTACs. Azido-PEG9-acid is a click chemistry reagent, it contains an Azide group and can undergo copper-catalyzed azide-alkyne cycloaddition reaction (CuAAc) with molecules containing Alkyne groups. It can also undergo strain-promoted alkyne-azide cycloaddition (SPAAC) reactions with molecules containing DBCO or BCN groups. | [IC 50]
