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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Study design
- Test substance input data:
- The following physico-chemical properties of the substance were used to calculate the distribution:
- molecular mass: 87.17 g/mol
- data temperature: 20 °C ( BASF AG, 1998; SIK-no.: 98/4896)
- log Kow: 1.32 (23°C, pH11, BASF SE, 2013; 11L00479)
- water-solubility: 1000000 g/m³ (25 °C) (BASF SE, 2013; 11L00479)
- Henry´s law constant: 1.5 Pa*m³/mol (estimated, EPI Suite v4.11, 2016)
- vapour pressure: 17250 Pa (20°C) (measured 20°C, BASF AG, 1998; SIK-no.: 98/4896)
- melting point: 20 °C (Gestis databank) - Environmental properties:
- see "Any other information on materials and methods incl. tables"
Results and discussion
Percent distribution in media
- Air (%):
- 34.5
- Water (%):
- 65.3
- Soil (%):
- 0.1
- Sediment (%):
- 0.1
Any other information on results incl. tables
Over time, the substance will preferentially distribute into the compartment water (65.3%) and air (34.5%)
The data refer to the uncharged molecule (pKa value: 9.25, measured). The substance is supposed to be charged under environmentally relevant conditions. Therefore the distribution into water may be still underestimated.
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.
