Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Description of key information
A measured Koc value of 3760 (log Koc 3.58) indicates that the substance has potential to adsorb to sediment/soil.
Henry coefficient: To assess the volatilisation potential of the substance a Henry's law constant was calculated using EUSES, which showed a value of 2.49 Pa. m3/mol (at 12 °C). Based on this value some partitioning from water to air may be expected.
Based on Level III environmental distribution modelling using EPISUITE (assuming equal and continuous releases to air, water and soil) using the CAS number 18479-57-7 and the measured physico-chemical parameters (water solubility and log Kow) as input, it is estimated that the majority of the substance released to the environment will partition mainly into soil (73.1%) and water (25.2%) with minor amounts to air (1.5%) and sediment (0.1%).
The SimpleTreat model (4.0) simulates the distribution of the substance in a Sewage Treatment Plant. Model calculations (default assumptions) show that 65.8% of the substance will be degraded and that 9.8%, 23.7% and 0.72% will partition to water, sludge and air, respectively.
Additional information
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.
