<p>Water-soluble salts of hydrazone compounds react quickly with aniline compounds in the presence of a peroxidase and hydrogen peroxide to provide a color which can be measured spectrophotometrically or visually, either in solution or when incorporated in a device for the measurement of analytes of interest. These water-soluble hydrazone salts are useful in determining hydrogen peroxide or an analyte which reacts to produce hydrogen peroxide in an aqueous liquid, by, in the presence of a substance having peroxidative activity, physically contacting a sample of a liquid with a dye-forming composition comprising a water-soluble salt of a hydrazone compound and a substituted or unsubstituted aniline compound to produce a colored dye; and detecting the dye formed as a result of the presence of hydrogen peroxide or an analyte which reacts to produce hydrogen peroxide.</p> |
