Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Hydrolysis as a function of pH
Key value for chemical safety assessment
- Half-life for hydrolysis:
- 182 d
- at the temperature of:
- 25 °C
Additional information
To fulfil this endpoint, read across is utilised to CAS 125643-61-0. Experimental studies on hydrolytic effects demonstrated that the substance does undergo hydrolysis at environmentally relevant pH’s, with a half life of 10.8 days at pH 4, 182 days at pH7 and 14.1 days at pH 9. As such, some minor degradation is anticipated via this route. Studies on direct phototransformation in water are not available, but it is assumed on the basis of chemical structure and nature of use that the substance is not degraded by direct photolysis. It is concluded, therefore, that abiotic processes would contribute to the depletion of the substance within the environment, although this is likely to be a slow process
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.
