N-(Azido-PEG3)-N-Boc-PEG4-t-butyl ester Chemical Properties, Uses, Production
Description
N-(Azido-PEG3)-N-Boc-PEG4-t-butyl ester is a branched molecule with a terminal azide group and a t-butyl ester group. Azide (N3) enables PEGylation via Click Chemistry. Boc group and the t-butyl protected carboxyl group can be deprotected under mild acidic conditions.
Uses
N-(Azido-PEG3)-N-Boc-PEG4-Boc is a PEG-based PROTAC linker that can be used in the synthesis of PROTACs[1]. N-(Azido-PEG3)-N-Boc-PEG4-Boc 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.
