Properties

Description

Propargyl-PEG4-S-PEG4-acid is a reagent grade PEG linker with a propargyl group and a terminal carboxylic acid, designed for copper-catalyzed azide-alkyne click chemistry reactions. The terminal carboxylic acid reacts with primary amine groups in the presence of activators (EDC, HATU, etc) forming a stable amide bond. The PEG spacer increases water solubility.
