Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Any other information on results incl. tables

The decomposition at pH 7 and pH 9 is higher than 50 % after 2.4 h at 50°C. Thus no further

investigations are necessary. According to the guideline, the test substance may be considered

hydrolytically instable at pH 7 and pH 9 and the half-life period, at 25°C, can be estimated as

lower than one day.
