Aminooxy-PEG1-azide Usage And Synthesis

Description

Aminooxy-PEG1-azide is a short PEG linkerwith two functional groups, aminooxy (ONH2) and azide(N3). Aminooxy group can be used in bioconjugation by reaction with an aldehyde to form an oxime bond. If a reductant is used, it will form a hydroxylamine linkage. The azide group can react with alkyne, BCN, DBCO via Click Chemistry to yield a stable triazole linkage. Aminooxy compounds are very reactive and sensitive; they cannot be stored for long term. Immediate use (within 1 week) is highly recommended.

Uses

Aminooxy-PEG1-azide is a PEG-based PROTAC linker can be used in the synthesis of PROTACs[1]. Aminooxy-PEG1-azide 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.
