This compound 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 serves as a linker or spacer in the synthesis of complex biomolecules, such as peptides, proteins, and antibodies, facilitating the attachment of functional groups or labels for research and diagnostic purposes. Additionally, it is employed in material science for surface modification and the development of functionalized polymers. Its PEG (polyethylene glycol) segment enhances solubility and biocompatibility, making it suitable for drug delivery systems and therapeutic agent design.
