This chemical is widely used in bioconjugation and click chemistry applications due to its azide functional group, which enables efficient and selective reactions with alkyne-containing molecules. It is particularly valuable in the synthesis of complex biomolecules, such as peptides, proteins, and polymers, where it serves as a linker or spacer. The Boc (tert-butoxycarbonyl) protecting group ensures stability during synthesis and can be easily removed under mild acidic conditions, allowing for further functionalization. Its PEG (polyethylene glycol) chain enhances solubility and biocompatibility, making it suitable for drug delivery systems, biotechnological research, and the development of therapeutic agents. Additionally, it is employed in the preparation of hydrogels, nanoparticles, and other advanced materials for biomedical applications.
