    Mercurochrome is in the Sigma catalogue.
    It is also in the Aldrich catalogue, but under
    its alternative name of merbromin. You might
    also find it in a pharmacy. I remember it
    being used as a topical antiseptic for abrasions
    in the 1960s: bright red and doesn't wash off.
    It is an organic mercury compound, so be careful
    with it.  LD50 (rabbit, i.v.) = 15-20 mg/kg.
    The amounts needed to mark specimens, however,
    should be minuscule.
