Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
In contact with water the substance will hydrolyze slowly.
Key value for chemical safety assessment
Additional information
The hydrolytical stability of an analogous compound was assessed in a study following OECD guideline 111 (BASF 2013). No hydrolysis was observed at pH 4 and pH 7 at a temperature of 50 °C. At pH 9 a decrease of test substance was observed. However, the degradation reaction measured in buffer pH 9 were no first or pseudo-first order. Therefore, kobs and half lives could not be calculated. As the UV signals in the test solutions could not significantly be correlated to hydrolysis- or other degradation products, it should be considered whether the decreasing signals of the test item in the pH 9 test solutions could also (at least partially) be caused by precipitation during the tests due to lower solubility in water at pH 9. A detailed read across justification is attached to the endpoint study record.
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.
