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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Additional information
The substance is not readily biodegradable. Hydrolysis of the substance cannot be directly measured by testing due to the high water insolubility but, based on the chemical structure, the substance is likely to bbe hydrolytically stable. On the basis of these factors, the substance is likely to be highly persistent in the aquatic and terrestrial environment.
Based on the available data, the substance is not toxic to any of the three tropic freshwater species tested. It is considered unlikely that the substance would be toxic to marine species.
The substance has a high partition coefficient and is predicted to have a low BCF. It is therefore considered that the substance would not have the potential to bioaccumulate in the environment.
Due to the above factors exposure of the substance to the environment is predicted to result in a low tendency to air or water, instead the substance is expected to bind tightly and persist in soil and sediment without further distribution to soil pore water.
Conclusion on classification
Based on the data avaialble the substance does not trigger any of the requirements for environmental classification. The substance is therefore not classified.
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.
