6-Azidohexan-1-ol is widely used in click chemistry applications, particularly in the synthesis of bioconjugates. Its azido group allows for efficient and selective reactions with alkynes via the copper-catalyzed azide-alkyne cycloaddition (CuAAC) reaction, making it valuable for labeling biomolecules such as proteins, peptides, and nucleic acids. This compound is also employed in material science for surface modification and functionalization of polymers, nanoparticles, and other materials to introduce specific properties or enable further chemical modifications. Additionally, it serves as a linker or spacer in drug delivery systems, facilitating the attachment of therapeutic agents to carriers or targeting molecules. Its versatility in crosslinking and bioconjugation makes it a useful tool in both research and industrial applications.
