Description
An iridescent green crystalline compound composed of mercuric acetate dibromide fluorescein. Merbromin forms a red aqueous solution that fluoresces a bright yellow green. Since its discovery in 1919, merbromin was widely used as a germicide and antiseptic under the common brand name of Mercurochrome. In 1990, the U.S. banned its sale due to potential of Mercury poisoning. Merbromin forms red stains that can be removed by washing first with permanganate solution and then with Oxalic acid solution (Merck Index, 1996).
