This compound is widely used in bioconjugation and click chemistry applications due to its azide functional group, which allows for efficient and selective reactions with alkyne-containing molecules. It serves as a linker in the synthesis of drug delivery systems, enabling the attachment of therapeutic agents to targeting molecules or nanoparticles. Additionally, it is employed in the development of proteomics tools, where it facilitates the labeling and identification of proteins. Its PEG (polyethylene glycol) spacer enhances solubility and reduces immunogenicity, making it suitable for use in biomedical research and therapeutic formulations.
