Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

Additional information
In a study designed to assess the hydrolytic stability of the test substance as a function of pH, it was determined in the pretest that the test substance was extremely unstable in water at pH7 (97.8% hydrolysis in 2.4h @50°C). Assuming the very rough rule of thumb that reaction rates double for every 10°C increase in temperature one can estimate the hydrolysis of the test substance at 20°C to be of the order of 5-6h, which is significantly <12h. Therefore, according to EC1907/2006, Annex VII, 7.7 column 2 the study does not need to be conducted.
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.
