Used in bioconjugation and click chemistry, it serves as a linker for attaching biomolecules or functional groups. It is particularly valuable in protein labeling, drug delivery systems, and polymer modification due to its azide group, which reacts efficiently in cycloaddition reactions. Additionally, it finds applications in surface functionalization and the development of bioorthogonal probes for imaging and diagnostics. Its versatility makes it a key component in advanced materials and biomedical research.
