Description of key information
Based on physico-chemical properties, the Henry's law constant was determined at 4.2E-06 Pa.m3/mol at 12 °C. This value indicates that the substance has a low volatility based on Lyman et al., 1982.
The adsorption coefficient (Koc) of the substance was experimentally determined at 2291 L/kg, corresponding to a log Koc at 3.36 (Bär, 2017). This result indicates that the substance is slightly mobile in soils, according to P.J. McCall et al., 1981 and FAO Mobility Classification (FAO, 2000; US EPA, 2006). In addition, with a log Koc > 3, the substance does not meet the Mobility (M) and very Mobile (vM) screening criteria of the new draft CLP proposal of September 2022.

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).
