Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Additional information
The available data on the stability of the substance indicate that the substance is not stable at environmental conditions. Based on the available test on ready biodegradability the substance is not readily biodegradable according to OECD criteria. Studies investigating the degradation processes in water/sediment systems determined a rapid degradation by microbially induced degradation. The reported half-lives for the water/sediment system were < 2 days. For the degradation in soils half-lives of 7-12 days were reported. Thus an accumulation of the substance in soils is not expected. The hydrolysis of the substance is pH-dependent and increases with increasing pH vlaue. At pH 7 a half-life of 40.9 days was determined. Whereas at pH 9 the determined half-live was 0.4 days.
For photodegradation in air a half-life of 1.96 days was calculated. However an evaporation of the substance to the atmosphere is not expected based on the low vapour pressure (VP: 6.3E-6 Pa at 20°C). Experimental data on photodegradation in water and soil are available. The determined environmental half-life (52° Northern latitude) was 17 days for sterile aqueous photolysis. For photodegradation in soil a DT50 of 5.6 days was estimated for outdoor conditions.
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.
