Sulfo-Cyanine7.5 is a near infrared, sulfonated cyanine dye with rigidized trimethylene chain. The fluorophore is structurally very similar to indocyanine green (ICG) dye that has been approved for human use. However, the dye has an improved quantum yield because of its rigidized structure.

This is an alkyne derivative for copper catalyzed Click chemistry.

Sulfo-Cyanine7.5 azide

Sulfo-Cyanine7.5 is a very hydrophilic and water soluble dye for the near infrared region. The absorption and emission spectra of the dye are similar to indocyanine green (ICG), but sulfo-Cyanine7.5 has a much higher fluorescence quantum yield. The dye is a great choice for near infrared in vivo imaging. This is an azide for Click chemistry.
