This compound is primarily utilized in bioconjugation and click chemistry applications. Its endo-BCN (bicyclo[6.1.0]nonyne) group enables efficient and selective reactions with azide-containing molecules, making it valuable for labeling, imaging, and drug delivery systems. The PEG2 (polyethylene glycol) spacer enhances solubility and reduces steric hindrance, improving the efficiency of conjugation. The alcohol functional group allows for further chemical modifications or attachment to other molecules. It is commonly used in the development of targeted therapies, diagnostic probes, and biomaterials, where precise and stable conjugation is essential. Its versatility makes it a key tool in chemical biology and pharmaceutical research.
