Azido-PEG23-amine(CAT: I016077) is a bifunctional polyethylene glycol (PEG) derivative containing an azide group and a terminal amine. The azide group enables copper-catalyzed azide-alkyne cycloaddition (Click Chemistry) with alkyne-functionalized compounds, facilitating the creation of stable triazole linkages. The amine group reacts with electrophiles, such as carboxylic acids or activated esters, to form amide bonds. The PEG23 spacer provides hydrophilicity and flexibility, enhancing solubility in aqueous systems and reducing nonspecific interactions. Azido-PEG23-amine is widely used in bioconjugation, surface modification, and the development of drug delivery systems, serving as a versatile tool for chemical and biomedical research.
