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 is particularly valuable in the development of peptide-based drugs, where it serves as a linker to attach bioactive peptides to other molecules or surfaces. The Boc (tert-butyloxycarbonyl) protecting group ensures stability during synthesis, while the PEG2 (polyethylene glycol) spacer enhances solubility and reduces steric hindrance, improving reaction efficiency. Its applications extend to the creation of targeted drug delivery systems, diagnostic probes, and biomaterials, making it a versatile tool in pharmaceutical and biomedical research.
