ATTO 532 azide is the azide derivative of ATTO 532, with maximum excitation/emission wavelengths of 532/552 nm. This compound serves as a click chemistry reagent featuring an azide group, enabling copper-catalyzed azide-alkyne cycloaddition (CuAAC) with alkynes. It can also engage in strain-promoted azide-alkyne cycloaddition (SPAAC) with molecules containing DBCO or BCN groups.
