Cy3-PEG2-exo-BCN

Description

Cy3-PEG2-exo-BCN is a dye derivative of Cyanine 3 Cy3 HY-D0822 containing 2 PEG units. Cy3-PEG2-exo-BCN contains the lyophilic bidentate macrocyclic ligand BCN, which can further synthesize macrocyclic complexes. In click chemistry, exo-BCN can react with molecules containing azide groups to form stable triazoles in the absence of catalysts.
