The invention comprises imidazo [4,5-b] quinoxaline quaternary salts of the general formula <FORM:1075654/C2/1> wherein R and R1 each represent an alkyl, including cycloalkyl, or substituted alkyl group containing 1 to 18 carbon atoms or an aryl or substituted aryl group, R2 represents an alkyl group containing 1 to 4 carbon atoms, an aralkyl group or an aryl group, and X represents chlorine, bromine or iodine. These salts may be prepared by condensing a quinoxaline compound of the general formula <FORM:1075654/C2/2> with an acyl halide of the formula R2COX. |
