Description
Azido-PEG3-CH2CO2-NHS consist of azide and NHS ester moieties The azide(N3) group is reactive with alkynes, BCN and DBCO via Click Chemistry to yield a stable triazole linkage. The NHS ester can label the primary amines (-NH2) of proteins, amine-modified oligonucleotides, and other amine-containing molecules.
Uses
Azido-PEG3-NHS ester is a PEG-based PROTAC linker that can be used in the synthesis of PROTACs[1]. Azido-PEG3-NHS ester 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.
