One experimental study according to EU Method C.4-E indicated that the test substance is not readily biodegradable according to the OECD criteria (5% biodegradation after 28 d). The degradation via abiotic hydrolysis is not considered to be a relevant degradation pathway in the environment since preliminary investigations according to OECD 111 showed that the substance is hydrolytically stable. No hydrolysis was recorded at pH 4, 7 and 9 and 50 °C. Extrapolation to 25 °C results in DT50 values > 1 yr at 25 °C for pH 4, 7 and 9.

Considering the water solubility of 3.89 g/L and the low potential for adsorption to organic soil and sediment particles (log Pow: 1.76), the main compartment for environmental distribution is expected to be the surface water.

Evaporation from the water phase into air and the transport through the atmospheric compartment is considered to be low based on the Henry’s Law Constant of 0.0082 Pa m³/mol at 20 °C.
