Uses: Enzymatic spectrophotometric determination of "water-soluble" reagent for hydrogen peroxide.

The new Trinder's reagent is a highly "water-soluble" aniline derivative, which is widely used in diagnostic testing and biochemical tests. It has several advantages over conventional color-producing reagents in the colorimetric determination of hydrogen peroxide activity. The new Trinder's reagent is stable enough to be used both in solution and in test line detection systems. In the presence of hydrogen peroxide and peroxidase, the new Trinder's reagent is in the oxidative coupling reaction with 4-aminoantipyrine (4-AA) or 3-methylbenzothiazole sulfone hydrazone (MBTH). A very stable purple or blue dye is formed. The molar absorbance of the dye coupled with MBTH is 1.5-2 times higher than that of the dye coupled with 4-AA; however, the 4-AA solution is more stable than the MBTH solution. The substrate is oxidized enzymatically by its oxidase to produce hydrogen peroxide. The concentration of hydrogen peroxide corresponds to the concentration of the substrate. Therefore, the amount of the substrate can be determined by the color development of the oxidative coupling reaction. Glucose, alcohol, acyl-CoA and cholesterol can be used to detect those substrates coupled with the new Trinder's reagent and 4-AA.
