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]

The FDA has banned Red Dye No. 3 dye from food and ingested drug products. Here are the food products containing Red 3 and how the ban affects you. Red Dye 3 Just Got Banned.
In flowers, the coloration that is provided by anthocyanin accumulation may attract a wide variety of animal pollinators, while in fruits, the same coloration may aid in seed dispersal by attracting herbivorous animals to the potentially-edible fruits bearing these red, blue, or purple colors.
Dicyanamide, also known as dicyanamine, is an anion having the formula C 2 N − 3.It contains two cyanide groups bound to a central nitrogen anion.The chemical is formed by decomposition of 2-cyanoguanidine.
When will red dye No. 3 be officially gone from shelves? The FDA is giving food companies until January 15, 2027, to remove red dye No.3 from their products, so it won't be officially gone until then.
Indocyanine green (ICG) is a cyanine dye used in medical diagnostics. It is used for determining cardiac output, hepatic function, liver and gastric blood flow, and for ophthalmic and cerebral angiography. [4] It has a peak spectral absorption at about 800 nm. [5]
