sulfo-Cyanine7.5 is a water-soluble, near-infrared fluorescent dye. The structure of the dye is similar to indocyanine green (ICG), but it contains a rigid trimethine linker increasing its fluorescence quantum yield.

This fluorophore is useful for near-infrared imaging. sulfo-Cyanine7.5 carboxylic acid contains a free carboxy group.
