Additional information

The substance was shown to be hydrolytically stable at pH 4, 5 and 7 at 25 °C. Under alkaline conditions (pH 9), the dissipation half-life was found to be 121 d. Thus, hydrolysis is not a route of degradation under environmental conditions. However, sunlight can be considered as the major abiotic degradation pathway in the aqueous environment with the photolytical half-life of the substance being 1.3 days. In soil a half-life of 34 days in artificial sunlight and 48 days in permanent darkness was recorded for the target substance. The main degradation products were sulfone and sulfonic acid.
