Cholesterol-PEG4-Azide is an amphiphilic PEG derivative designed for drug delivery, particularly in liposome formulations. Its lipid component enables hydrophobic drug encapsulation, while the azide group facilitates bioconjugation via CuAAC or SPAAC click chemistry for targeted applications. The PEG4 chain increases the solubility of the molecule. Reagent grade, for research purpose.
