Propargyl-PEG10-t-butyl ester Chemical Properties, Uses, Production

Description

Propargyl-PEG10-t-butyl ester is a crosslinking reagent that can react with azide-bearing compounds or biomolecules via copper catalyzed Click Chemistry reactions. The carboxyl group can be deprotected under acidic conditions.

Uses

Propargyl-PEG10-Boc is a PEG-based PROTAC linker that can be used in the synthesis of PROTACs[1]. Propargyl-PEG10-Boc is a click chemistry reagent, it contains an Alkyne group and can undergo copper-catalyzed azide-alkyne cycloaddition (CuAAc) with molecules containing Azide groups.

IC 50

PEGs; Alkyl/ether
