Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 700 L/kg w.w. (log Koc 2.85) indicates that the substance has low potential to adsorb to sediment/soil (value is =< 3, ECHA guidance 7b, section 7.8.7).
The Henry's law constant is calculated using the equation from EUSES. Using a molecular weight of 168 g/mol, and the experimentally determined vapour pressure of 9.91 Pa (at 23 °C) and water solubility of 85 mg/L (at 23 °C) the Henry's law constant at 25oC and at environmental temperature (12 °C) is calculated to be 20 and 9.4 Pa·m³/mol, respectively.
Based on Level III environmental distribution modelling using EPISUITE (assuming equal and continuous releases to air, water and soil) using the CAS number 14576 -08 -0, it is estimated that the majority of the substance released to the environment will partition mainly into soil (84.4%) and water (15.2%) with minor amounts to sediment and air (both <1%).
The SimpleTreat model, which is incorporated in EUSES, simulates the distribution of the substance in a Sewage Treatment Plant. Model calculations show that 80% of the substance will be degraded and that 6%, 11.1% and 2.6% will partition to sewage sludge, water and air, respectively, including measured Koc.
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.
