This chemical is primarily used in the field of bioconjugation and click chemistry due to the presence of an azide group, which allows for efficient and selective reactions with alkyne-functionalized molecules. It is often employed in the modification of biomolecules, such as proteins, peptides, and nucleic acids, enabling the attachment of fluorescent dyes, affinity tags, or other functional groups for research and diagnostic purposes. Additionally, it finds applications in materials science for surface functionalization and the development of advanced polymers or nanomaterials. Its water-soluble nature and biocompatibility make it suitable for use in biological and biomedical studies.
