N-(Azido-PEG3)-N-Boc-PEG3-t-butyl ester

Description

N-(Azido-PEG3)-N-Boc-PEG3-t-butyl ester is a protected multifunction linker. The azide group enables PEGylation via Click Chemistry. Boc and the t-butyl protected carboxyl group can be deprotected under mild acidic conditions.

Uses

N-(Azido-PEG3)-N-Boc-PEG3-t-butyl ester is a PEG-based PROTAC linker that can be used in the synthesis of PROTACs[1]. N-(Azido-PEG3)-N-Boc-PEG3-t-butyl 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.
