Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Additional information
An experimentally determination of the adsorption coefficient according to OECD TG 121 is not possible, as the substance is insoluble or only poorly soluble in water and using a co-solvent, the test item immediately precipitates after contact with water. Therefore, the adsorption coefficients were calculated using the software KOCWIN v2.00 owned by the U.S. Environmental Protection Agency on the basis of the structural formula of the test item components and possible hydrolysis products. Based on the results, the log Koc of the substance is expected to be higher than 10, indicating a high potential for adsorption.
The Henry's Law Constant of the substance is calculated to be 0.0000146 Pa m³/mol at a temperature of 25 °C. It is directly calculated as a ratio of the calculated vapour pressure (VP, 2.19E-08 Pa) to the measured water solubility (c, 3 mg/l). The molecular weight (MW, 1998 g/mol) of the test item was also used for estimation. The substance is low volatile from surface waters.
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.
