Study design

Test substance input data:
The following physicochemical properties of the substance were used to calculate the distribution:

- Molar mass: 152.24 g/mol
- Data temperature: 25 °C
- Water solubility: 1.0E+06 g/m³ (measured @23°C; BASF, 2013; report no. 11L00314)
- Vapour pressure: 2.67 Pa (@ 25 °C, measured; BASF AG, 2013; report no. 11L00314)
- log Pow: -2.2 (@25°C, pH 7.0; BASF AG, 1989; report no. 110187/01)
- Melting point: 40.59°C (MPBPVP v1.43 of EPI Suite v4.10)
- Henry´s law constant: 4.06E-04 Pa*m³/mol (calculated by Mackay Level I)
