Description of key information

The QSAR determination of the carbon partition coefficient for 6-Chlor-Chlormethyldien using the model KOCWIN included in the Estimation Program Interface (EPI) Suite v4.1 revealed a value of 6400 L/kg; logKoc=3.806 (Kow method) for the unaffected molecule of the substance as any decomposition (e.g. hydrolysis) of the substance is not taken into account by the program.
