Cy3-PEG3-Azide

Cy3-PEG3-Azide is a derivative of the Cyanine 3 (Cy3) dye, featuring 3 PEG units. This compound contains an Azide group, enabling it to participate in copper-catalyzed azide-alkyne cycloaddition reactions (CuAAc) with molecules bearing an Alkyne group. Additionally, Cy3-PEG3-Azide can undergo strain-promoted alkyne-azide cycloaddition reactions (SPAAC) with molecules that have DBCO or BCN groups.
