Description and Uses
Azido-PEG4-acid is a very popular PEG reagent containing an azide group with a terminal carboxylic acid. The hydrophilic PEG spacer increases solubility in aqueous media. The azide group can react with alkyne, BCN, DBCO via Click Chemistry to yield a stable triazole linkage. The terminal carboxylic acid can react with primary amine groups in the presence of activators (e.g. EDC, or HATU) to form a stable amide bond.
Azido-PEG4-Acid is amine- or phosphine-reactive building block used to derivative primary amines for ligation to alkyne-tagged molecules.
