Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 potential of the test substance to undergo hydrolytic degradation in an aquatic environment was studied in GLP conformance according to the procedures outlined in EEC's Annex V, Part C.7.2 and OECD Guideline No. 111. A Preliminary Test was performed at 50.0 ± 0.5 °C at three pH values: 4, 7, and 9. The test solutions were analyzed for the test substance using high performance liquid chromatography with ultraviolet light detection (HPLC/UV). The change in test substance concentration, over time, was calculated and reported as the percent hydrolysis. Less than 10 percent hydrolysis was observed in the pH 4, 7, and 9 test systems after 120 hours, therefore no further testing (Test 1, Test 2, or Test 3) was required.
The test substance is hydrolytically stable (half-life greater than one year) at 25°C.
Key value for chemical safety assessment
Additional information
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.
