Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 hydrolysis behaviour of the substance could not be examined according to the OECD TG 111, as the substance is not sufficiently soluble in water, no analytical method could be developed to analyse the test substance concentrations and additionally, the substance precipitates in water and organic solutions. During the examination it was found that the substance was stable towards hydrolysis as no hydrolysis or decomposition during precipitation occurs, by comparing the IR-spectrum of the dried precipitate and the original test item.


A test on ready biodegradability showed that 47 % of the substance is degraded within 28 days. These results show that the substance is not readily biodegradable, but additionally provided evidence from an inherent test show that the substance can be degraded in sewage treatment plants. The substance is not readily biodegradable but inherent biodegradable with 78 % degradation within 28 days.


There is no measured data available on aquatic/sediment bioaccumulation of the substance. However, according to expert judgment, no bioaccumulation potential of this substance is expected.


As experimentally determination of the adsorption coefficient according to OECD TG 121 is not possible the adsorption coefficients were calculated on the basis of the structural formula of the test item components. 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.
