sulfo-Cyanine7.5 is a near-infrared, sulfonated cyanine dye with a rigidized trimethylene chain. The fluorophore is structurally similar to the Indocyanine Green (ICG) dye approved for human use. However, sulfo-Cyanine7.5 has an improved quantum yield because of its rigid structure.

This is an alkyne derivative for copper-catalyzed click chemistry reaction. sulfo-Cyanine7.5 is a very hydrophilic and water-soluble dye. The reagent is useful for labeling biomolecules and in vivo imaging.
