A method is suggested for selective determination of aromatic nitroso compounds based on titration with tin dichloride solution in glycerol, the substance to be determined being dissolved in absolute ethanol saturated with dry hydrogen chloride. The titration end point was determined potentiometrically, amperometrically, or visually using phenoxazine type redox indicators.
