Propargyl-PEG4-amine(CAT: I014611) is a functionalized polyethylene glycol (PEG) linker featuring a propargyl group for copper-catalyzed azide-alkyne cycloaddition (CuAAC), commonly known as “click chemistry,” and a primary amine group for conjugation to carboxyl or other reactive groups. The PEG4 spacer provides enhanced solubility, flexibility, and reduced steric hindrance, making it ideal for bioconjugation and drug delivery applications. This compound is particularly valuable in chemical biology and bioconjugation research, facilitating the synthesis of biomolecule conjugates, targeted probes, and multifunctional materials. Propargyl-PEG4-amine is an essential tool for advancing research in molecular labeling, targeted therapeutics, and material science.
