Abstract
A 3-aminobenzoic acid or a 3-aminobenzenesulfonic acid, when reacted with a 4-aminoantipyrine in aqueous medium in the presence of hydrogen peroxide forms a novel colored dye which is believed to be a charge-transfer complex of free radicals formed from the 3-aminoaromatic acid and the 4-aminoantipyrine. The dye and the process by which it is produced are useful in analytical procedures for hydrogen peroxide, as well as in enzymatic analyses involving the formation of hydrogen peroxide.
