Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Estimated half-life at 25 °C at pH4, pH 7 and pH 9 : greater than one year
Key value for chemical safety assessment
- Half-life for hydrolysis:

- at the temperature of:
- 25 °C
Additional information
The experimental determination was carried out according to Method C7 Abiotic Degradation, Hydrolysis as a Function of pH of Commission Regulation (EC) No 440/2008 of 30 May 2008, Method 111 of the OECD Guidelines for Testing of Chemicals, 13 April 2004 and GLP. No deviation from the guidelines were observed during the test.
The test system uses sterile buffer solutions at pH 4.0, 7.0 and 9.0. The test item was dissolved in an aqueous solution at a specific pH value (4.0, 7.0 and 9.0) and was incubated in the dark and at a specific temperature, in a water bath thermostated at 50 ± 0.5 °C. The concentration of the test item was determined as a function of time, using a HPLC-MS method. The estimated half-life at 25 °C of the test item for pH 4, 7 and 9 has been shown to be greater than 1 year.
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.
