Description of key information

Additional information

Phototransformation

After evaporation or exposure to air, the substance will be rapidly degraded by photochemical processes (half-life = 3.9 h).

Hydrolysis

According to structural properties, hydrolysis is not expected. A study does not need to be performed since the substance is readily biodegradable.

Biodegradation

The substance is readily biodegradable (according to OECD criteria).

Bioaccumulation

Accumulation in organisms is not to be expected.

Adsorption/Desorption

Adsorption to solid soil phase is not expected. Moreover, the chemical is readily biodegradable.

Henry's Law Constant

From the water surface, the substance will not evaporate into the atmosphere.

Distribution modelling

Over time, the substance will preferentially distribute into the compartment water (99.2%) and air (0.8%); the data refer to the uncharged molecule (pKa value: 10.1).However, since the substance will be ionized under environmentally relevant conditions, the distribution into water may still be underestimated.
