One experimental study according to OECD 310 indicated that the substance is “readily biodegradable”. A degradation of 62% was recorded after 28 d. The degradation via abiotic hydrolysis is not considered to be a relevant degradation pathway in the environment. An experimental study according to OECD 111 confirmed that the substance is hydrolytically stable under environmental conditions at pH 4 and pH 7. For pH 9 a DT50 of 29 d at 25 °C was calculated using the Arrhenius equation.
Considering the water solubility of 21 mg/L and the low to moderate potential for adsorption to organic soil and sediment particles (log Koc: 2.37 - 3.29, mean: 2.83, KOCWIN v2.00), the substance is expected to distribute to the surface water with potential to adsorption to particulate matter. However, the Henry’s Law Constant of 49.5 - 75.6 Pa m³/mole at 25 °C as well as the vapour pressure of 36.87 Pa at 20 °C (OECD 104) indicate potential for volatilization of the substance from the water phase to the atmospheric compartment.
