Used in bioconjugation and click chemistry applications, this compound serves as a linker for attaching molecules to biomolecules like proteins or antibodies. Its endo-BCN group enables efficient and selective reactions with azide-containing compounds, while the PFP ester allows for stable amide bond formation with amines. Commonly applied in drug delivery systems, diagnostic probes, and targeted therapies, it facilitates the development of precise and functional bioconjugates. Its PEG2 spacer enhances solubility and reduces steric hindrance, improving overall reaction efficiency and biocompatibility.
