5. APPLICABILITY DOMAIN
For details see Mackay, D. (2001); Mackay et al. (1996)

6. ADEQUACY OF THE RESULT
A Level I calculation is not required under REACh but gives a general impression of the likely media into which a chemical will tend to partition and an indication of relative concentrations in each medium.

Any other information on results incl. tables

Over time, the substance will preferentially distribute into the compartment Water (99.9%) and slightly into the compartment Air (0.1%).

The data refer to the uncharged molecule. However, at environmentally relevant pH conditions the substance will be ionised (calculated pKa value 1: 10.4) and the model might underestimate the distribution into water.
