Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

4. SCIENTIFIC VALIDITY OF THE (Q)SAR MODEL
For details see Mackay, D. (2001); Mackay et al. (1996)

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.

Results and discussion

Percent distribution in media

Water (%):
100

Any other information on results incl. tables

Over time, the uncharged substance will preferentially distribute into the compartment water (100%).

However, since the substance will be ionized under environmentally relevant conditions, the distribution into water may still be underestimated.
