Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 stability of the substance in air and water is low. The QSAR calculated rate constant for the OH sensitized photodegradation of the substance is approximately 50.2550 E-12 cm3/(molecule * s). At 500,000 OH radicals / cm3, this corresponds to a half-life of 7.7 hours. The hydrolysis of the substance was tested according to OECD TG 111 (2004) and EU Method C.7 (2008). The test substance was found to be not hydrolytically stable. Half-lives at pH 4 and pH 9 were significantly below 10 minutes at 20 °C. The half-life at pH 7 was 449 (433-466) minutes at 20 °C, 225 (220-230) minutes at 30 °C and 87.0 (81.6-92.4) minutes at 40 °C. The correlation coefficients r2 were 0.996, 0.997 and 0.994 at these temperatures, confirming pseudo-first order kinetics.
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.
