Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

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

- Molar mass: 107.16 g/mol
- Data temperature: 20 °C
- Water solubility: 1000000 g/m³ (Ullmann, 2006)
- Vapour pressure: 60 Pa (@ 20°C, measured; Koeppe, 2009 / cited from LANXESS)
- log Pow: 1.00 (measured @25°C, pH 9.8-10.4; BASF AG, 1989; report no. BRU 89.096)
- Melting point: -0.64°C (MPBPVP v1.43 of EPI Suite v4.11)
- Henry´s law constant: 6.43E-03 Pa*m³/mol (Mackay Level I)
