Merbromin (MB)

Merbromin  is a topical antiseptic used for minor cuts and scrapes. Merbromin is an organomercuric disodium salt compound and a fluorescein. Merbromin"""s best-known use is as a topical antiseptic. It is still an important antiseptic, particularly in developing nations, due to its “unbelievably low cost”. Merbromin is also used as a biological dye to mark tissue margins and as a metal dye in industrial dye penetrant inspection to detect metal fractures. Mercurochrome is a trade name of merbromin. The name is also commonly used for over-the-counter antiseptic solutions consisting of merbromin (typically at 2% concentration) dissolved in either ethyl alcohol (tincture) or water (aqueous). The chemical soon became popular among parents and physicians for everyday antiseptic uses, and it was commonly used for minor injuries in the schoolyard.
