The compound known as BCN-PEG4-Cyanine3 possesses an operational group termed bicyclononyne, which is connected to a Cyanine3 fluorophore. The unique structure of Bicyclo[6.1.0]nonyne, or BCN for short, classifies it as a subtype of cyclooctyne and significantly enhances its reactivity profile when it comes to strain-promoted azide-alkyne cycloaddition.
