Propargyl-PEG13-acid Chemical Properties, Uses, Production
Description
Propargyl-PEG13-acid consists of an alkyne group and a carboxylic acid. The carboxylic acid reacts with amine groups to form amide bonds in the presence of EDC or HATU as an activator. The alkyne group is commonly used in copper catalyzed azide-alkyne Click Chemistry reactions. The hydrophilic PEG units enhance the solubility of the molecule in aqueous media.
Uses
Propargyl-PEG-acid is a PEG-based PROTAC linker that can be used in the synthesis of PROTACs[1].
