Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
According to a Mackay Level I model calculation, the main target compartment for the substance will be the air (96.997 %). The calculated Henry’s Law constant of 140.74 Pa m³/mol at 20 °C indicates high volatility of the substance from surface waters. With a log Koc of 2.7 l/kg, a low sorption potential of the substance to soil or sediment organic matter is expected (Blume scale).
The QSAR calculated rate constant for the OH sensitized photodegradation of the substance is approximately 129.31E-12 cm3/(molecule * s). At 500,000 OH radicals / cm3 (approximate 24-hour mean in central Europe), this corresponds to a half-life of 3.0 hours. Hydrolysis under environmental conditions is extremly slow.
No ready biodegradation was observed in a study. The partition coefficient 1-octanol/water was determined as log Kow = 3.58 at 25 °C,
indicates that a significant bioaccumulation is not to be expected

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.
