Product Description:
FD & C Blue No. 2 is principally the disodium salt of 2-( 1,3-dihydro-3-oxo-5-sulfo-2H-indol-2-ylidene)-2,3-dihydro3-oxo-lH-indole-5-sulfonic acid.
The colorant is a blue-brown to red-brown powder that dissolves in water to give a solution that is blue at neutrality, blue-violet in acid, and green to yellow-green in base. When dissolved in concentrated sulfuric acid, it yields a blue-violet solution that turns blue when diluted with water. It is soluble in 95% ethanol.
FD & C Blue No. 2 is used in dessert powders, bakery goods, cereals, snack foods, confectionery products, maraschino cherries, sausage, ice cream, sherbet, and dairy products. The color is also used in drug preparations

Indigo carmine in a 0.2% aqueous solution is blue at pH 11.4 and yellow at 13.0. Indigo carmine is also a redox indicator, turning yellow upon reduction. Another use is as a dissolved ozone indicator through the conversion to isatin-5-sulfonic acid.This reaction has been shown not to be specific to ozone, however: it also detects superoxide, an important distinction in cell physiology. It is also used as a dye in the manufacturing of capsules.
In obstetric surgery, indigo carmine solutions are sometimes employed to detect amniotic fluid leaks. In urologic surgery, intravenous injection of indigo carmine is often used to highlight portions of the urinary tract. The dye is filtered rapidly by the kidneys from the blood, and colors the urine blue. This enables structures of the urinary tract to be seen in the surgical field, and demonstrate if there is a leak. However, the dye can cause a potentially dangerous increase in blood pressure in some cases.
