Aminooxy-PEG3-propargyl has a alkyne group and an aminooxy group. The aminooxy group reacts with aldehydes or ketones to form a stable oxime linkages. The alkyne group can participate in copper catalyzed azide-alkyne Click Chemistry reactions. Aminooxy compounds are very reactive and sensitive; they cannot be stored for long term. Immediate use (within 1 week) is highly recommended.

Aminooxy-PEG3-propargyl is a PEG-based PROTAC linker that can be used in the synthesis of PROTACs[1]. Aminooxy-PEG3-propargyl is a click chemistry reagent, it contains an Alkyne group and can undergo copper-catalyzed azide-alkyne cycloaddition (CuAAc) with molecules containing Azide groups.
