Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
No significant hydrolytic degradation was observed to occur in pH buffers 5, 7 or 9 at 50°C (t1/2 >1 year). In another test at pH 4, the test substance degraded at 25°C with a t1/2 of 11 weeks, decreasing to ca 2 weeks at 40°C and In a third test, the half-life at pH 4 and 50°C was 5 days. In phototransformation studies in water, the test substance degraded with a ½ life of 18 minutes. Low water solubility combined with rapid aqueous photolysis suggest that the test substance will have minimal impact on the aquatic environment. The t1/2 estimated for test substance under natural sunlight conditions (>1 year; spring at Letcombe, England) has indicated that soil photolysis will not be a significant route of degradation for the test substance in the environment.
The test substance is not readily biodegradable. After 28 days of incubation with activated sludge, the test substance degradation reached a maximum mean of 3% ThCO2. Under aerobic conditions in surface water, DT50s ranged from 3 days in sandy loam, 7 days in clay loam, 15 days in the Goose River, 47 days in the Golden Lake, and up to 128 days in neutral pond water. DT50s of the test substance in soil ranged from 110 days to 17 months.
The measured bioconcentration factor (BCF) in whole fish for the test substance was 5040 L/kg in rainbow trout.
The vapour pressure and Henry’s law constant of the test substance indicate that it has no potential to volatilize and therefore would not have any global warming potential (GWP), ozone depleting potential (ODP), photochemical ozone creation potential (POCP) or be expected to accumulate in the troposphere. The test substance is not listed in Annex I to Regulation (EC) No 2037/2000 of the European Parliament and of the Council of 29 June 2000 on substances that deplete the ozone layer and its subsequent amendments.
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.
