Cy7 is a near-IR fluor that is invisible to the naked eye (excitation/emission maximum 750/776 nm). It is used in in vivo imaging applications, as well as the Cy7.5 dye. Sulfo–cyanine dyes bear one or two sulfo groups, rendering the Cy dye water-soluble, but tri- and quadri-sulfonated forms are available for even higher water solubility. [8]

Pinacyanol is a cyanine dye. It is an organic cation, typically isolated as the chloride or iodide salts. The blue dye is prepared from 2-methylquinoline by quaternization with ethyl chloride or ethyl iodide. Condensation with formaldehyde results in coupling. Subsequent oxidation of the leuco intermediate gives the dye. [1]
