Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Following the preliminary test OECD 111 (5 days incubation at 50°C at pH values 4, 7 and 9), the test item is considered to be stable at pH 4. It was not possible to determine the hydrolysis at pH 7 and pH 9 due to a non-hydrolytic decomposition of the test item (change of colour, likely an oxidative process).
Key value for chemical safety assessment
Additional information
The test item was tested for hydrolysis according to the OECD Guideline 111 and GLP. The preliminary test was performed at 50°C and pH 4, 7 and 9.
Since less than 10% of hydrolysis was observed at pH 4, the test item is considered stable at pH 4 and no additionnal test is required.
At pH 7 and 9, the test item stability was evaluated via the recovery rates which were 89 and 88,1 % respectively. It was not possible to determine the hydrolysis because non-hydrolytic decomposition of the test item occurs (change of colour of the tested solutions), that is likely an oxidative decomposition.
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.
