Azido-PEG-azide

Azido-PEG-azide is a functional group that is widely used in pharmaceutical research and development. It belongs to the class of azides, which are chemical compounds that contain a nitrogen atom connected to two other atoms via a triple bond. Azido-PEG-azide is unique because it contains two azide groups, which makes it a bifunctional compound. The presence of PEG (polyethylene glycol) provides water solubility and enhances the pharmacokinetics of the molecule. Azido-PEG-azide is typically used in the development of drug delivery systems, where it can be conjugated with other molecules to form prodrugs, nanocarriers, or targeted drug delivery systems. In addition, it is used in the development of imaging agents, such as fluorescent probes or MRI contrast agents.
