In the study of ligand, polypeptide synthesis support, a graft polymer compounds, new materials, and polyethylene glycol-modified functional coatings and other aspects of the active compound. Bromo-PEG4-azide (Br-PEG4-N3) is a bifunctional PEG derivative featuring a bromo group at one end and an azide group at the other. This compound is particularly valuable in click chemistry and bioconjugation applications due to the high reactivity of both functional groups. The bromo group can participate in nucleophilic substitution reactions, allowing for the attachment of various molecules or functional groups, while the azide group is ideal for copper-catalyzed azide-alkyne cycloaddition (CuAAC) reactions, a type of click chemistry.
