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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

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
- Air (%):
- 0.05
- Water (%):
- 99.9
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 (0.05%).
The substance will be ionized at lower environmentally pH, so the distribution into water may be appropriate.
The data refer to the uncharged molecule (measured pKa value: 9.30, Harlan, 2012, rep. no.: 41202877)
Applicant's summary and conclusion
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
