Abstract: A method of treating an animal having a condition associated with the presence of cyanide in quantities sufficient to cause undesirable symptoms which comprises administering to the subject a compound in an amount effective to alleviate the undesirable symptoms, the compound having the structure: ##STR1## wherein R.sup.1 and R.sup.1' are the same or different and each is an alkyl group, a phenyl group or a substituted derivative of a phenyl group;R.sup.2 and R.sup.2' are the same or different and each is hydrogen, an unbranched alkyl group, a halide or a group having the structure R--C-- ##STR2## wherein R is hydrogen, an alkoxide group, and alkyl group or OH; R.sup.3 and R.sup.3' are the same or different and each is hydrogen or an alkyl group;X and X' are the same or different and each is a water-soluble group having weak to intermediate field strength; andQ.sup.- is a soluble, pharmaceutically acceptable negative ion.
