Merbromin (marketed as Mercurochrome, Merbromine, Mercurocol, Sodium mercurescein, Asceptichrome, Supercrome, Brocasept and Cinfacromin) is an organomercuric disodium salt compound used as a topical antiseptic for minor cuts and scrapes and as a biological dye.
An antiseptic (Greek: ἀντί, romanized: anti, lit. 'against' [ 1 ] and σηπτικός , sēptikos , 'putrefactive' [ 2 ] ) is an antimicrobial substance or compound that is applied to living tissue to reduce the possibility of sepsis , infection , or putrefaction .
Bromine is used in cooling towers (in place of chlorine) for controlling bacteria, algae, fungi, and zebra mussels. [72] Because it has similar antiseptic qualities to chlorine, bromine can be used in the same manner as chlorine as a disinfectant or antimicrobial in applications such as swimming pools.
Commercially available organobromine pharmaceuticals include the vasodilator nicergoline, the sedative brotizolam, the anticancer agent pipobroman, and the antiseptic merbromin. Otherwise, organobromine compounds are rarely pharmaceutically useful, in contrast to the situation for organofluorine compounds. Several drugs are produced as the ...
Bond energies to bromine tend to be lower than those to chlorine but higher than those to iodine, and bromine is a weaker oxidising agent than chlorine but a stronger one than iodine. This can be seen from the standard electrode potentials of the X 2 /X − couples (F, +2.866 V; Cl, +1.395 V; Br, +1.087 V; I, +0.615 V; At, approximately +0.3 V).
(±)-2-Bromobuyric acid may be prepared by the acid-catalyzed Hell–Volhard–Zelinsky reaction, where butyric acid is treated with elemental bromine. It is one of many compounds that arise adventiously from the use of bromine as an antiseptic.
