Thiomersal: An organomercury compound used as a preservative in some vaccines and medical products. Both compounds contain mercury, but thiomersal has different uses and chemical structure.
Antiseptic: A substance applied to living tissue to reduce or stop the growth of microorganisms. Merbromin was used on skin for this purpose.
Johns Hopkins Hospital: A teaching hospital in Baltimore founded in 1889. Merbromin was developed by Hugh H. Young while he worked at Johns Hopkins.
Povidone-iodine: An iodine-containing antiseptic used to reduce microorganisms on skin and wounds. It became a widely used alternative to merbromin for topical antisepsis.
Mercury(II) chloride: A highly toxic inorganic mercury salt once used as a disinfectant and laboratory reagent. It illustrates why mercury-containing antiseptics raise safety concerns, despite differing from merbromin.
Mercury: A chemical element with symbol Hg and atomic number 80, whose compounds have diverse biological effects. Mercury is the toxic metal incorporated into merbromin’s molecular structure.
