Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 Koc of the substance is estimated to be 1283 L/kg (geometric mean of three QSAR results).

Key value for chemical safety assessment

Koc at 20 °C:
1 283

Additional information

There are no experimental value for adsorption/desorption. Estimated values have been generated by QSAR Methods. The calculation methods and Koc values are reported here below:

Estimation of Log Koc by TGD (2003) Equation for predominantly non hydrophobic: Log Koc = 3.411, Koc = 2582 L/kg

MCl Method from KOCWIN v2.00: Log Koc = 2.85, Koc = 715.1 L/kg

Log Kow Method from KOCWIN v2.00 (Input logKow = 4.6): Log Koc = 3.06, Koc = 1143 L/kg

A key value for chemical safety assessment is calculated by the geometric mean of the values cited above:

Geometric mean of Koc = 1283 L/kg

This gives a Log Koc = 3.108

[LogKoc: 3.108]
