Azido-PEG10-alcohol is widely used in bioconjugation and chemical biology due to its azide functional group, which allows for efficient click chemistry reactions. It is particularly valuable in the synthesis of modified biomolecules, such as peptides, proteins, and nucleic acids, enabling the attachment of labels, probes, or other functional groups. This compound is also employed in the development of drug delivery systems, where its PEG (polyethylene glycol) spacer enhances solubility and biocompatibility. Additionally, it plays a role in surface modification and the creation of functionalized materials for biomedical applications, including biosensors and tissue engineering scaffolds. Its versatility makes it a key reagent in research and industrial settings.
