Azido-PEG4-alcohol is a bifunctional polyethylene glycol derivative featuring both an azide group and a terminal hydroxyl group. The azide moiety enables facile incorporation via click chemistry, particularly useful in bioconjugation and labelling strategies. The PEG4 spacer imparts hydrophilicity and molecular flexibility, which can reduce steric hindrance and improve solubility in aqueous environments. Frequently employed in drug delivery research, surface modification, and bio-orthogonal chemistry, this reagent plays a pivotal role in constructing multifunctional biomolecules and advanced materials.
