Description of key information
Calculation with KOCWIN v2.00 (EPIWIN software by US-EPA), organic-normalized sorption coefficient (Koc): 10 L/kg (MCI method estimation)
Key value for chemical safety assessment
- Koc at 20 °C:
- 10
Additional information
The substance has a log Pow < 3 (log Pow <0.3; OECD Guideline 117, EU-Method A.8; see IUCLID section 4.7). Hence, the conduction of the study has been waived and the key value was determined by QSAR estimation [with KOCWIN v2.00 (EPIWIN software by US-EPA)]. The program estimates the organic-normalized sorption coefficient for soil, which is designated as Koc. The following two models are used: the Salbjic molecular connectivity (MCI) method as well as the traditional method which is based on the logPow value of the substance. The traditional method gives a value of 2.977 L/kg. The MCI method is taken more seriously into account, due to the fact that is includes improved correction factors, resulting in a Koc value of 10 L/kg (corrected log Koc = 0.95). It is noted that these results represent a best-fit to the majority of experimental values, due to the fact that the Koc of this structure may be sensitive to the surrounding pH. According to these results, the substance has a low sorption onto soil organic matter.

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.
