Activité biologique
N-Ethyl-N-(3-sulfopropyl)-m-anisidine sodium can be used for the detection of glycerol content. Catalyzed by peroxidase (POD), N-Ethyl-N-(3-sulfopropyl)-m-anisidine sodium can undergo a coupling reaction with hydrogen peroxide and 4-aminoantipyrine to produce a purple dye. The amount of the purple dye generated is related to the initial content of glycerol in the system. By measuring the absorbance of the purple dye at a specific wavelength (540 nm) using colorimetry, the concentration of glycerol can be indirectly determined[2].
