CY7-N3 (Sulfo-Cyanine7-N3) is a water-soluble Near-Infrared (NIR) dye azide designed for Click Chemistry. It possesses an azide group, enabling it to participate in copper-catalyzed azide-alkyne cycloaddition (CuAAc) reactions with alkyne-containing molecules. Additionally, it can undergo ring strain-promoted alkyne-azide cycloaddition (SPAAC) with molecules containing DBCO or BCN groups.
