Azido-PEG4-NHBoc Chemical Properties, Uses, Production
Description
t-Boc-N-Amido-PEG3-azide is a PEG reagent containing an azide group and Boc-protected amino group, it is reactive with alkyne, BCN, DBCO via Click Chemistry. The Boc group can be deprotected under mild acidic conditions to form the free amine.
Uses
Boc-N-Amido-PEG3-azide is a PEG-based PROTAC linker that can be used in the synthesis of PROTACs[1]. Boc-N-Amido-PEG3-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.
Definition
ChEBI: Tert-Butyl (2-(2-(2-(2-azidoethoxy)ethoxy)ethoxy)ethyl)carbamate is a carbamate ester.
