Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
The molecule is not expected to adsorb to suspended solids and sediment based upon the log Koc as calculated for the uncharged molecule. Aditionally, a pka values of 4.6 and 5.6 indicates that the molecule will predominantly exist as a anion in the environment and anions generally adsorb less to soils containing organic carbon and clay.
If the substance is exposed to water, it will notevaporate into the atmosphere from the water surface because of its Henry's Law Constant of0.0000087Pa m³/mol(25 °C).
Due to the results of the Mackay LEVEL 1 calculation, over time the substance will preferentially distribute into water (99.5 %).
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.
