Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Endpoint summary

Description of key information
Hydrolysis: No significant decrease in test item concentration by hydrolysis in freshwater was detected over 28 days.
Biodegradation: Although the test item was not readily biodegradable in an OECD 301F test, simulation studies in natural freshwater-sediment systems show that the test item is not persistent. DT50 values of 25.6 to 30.8 days have been reported for rivers and lakes in China, and a DT50 of 33 days was reported for a groundwater aquifer in Australia under aerobic conditions.
Bioaccumulation: A maximum BCF value of 801 L/kg was reported as the peak concentration of test item in mussels during the uptake period.
Adsorption / desorption: The mean log Koc was determined to be 3.70 ± 0.06 at 21°C.
Henry's Law constant: The Henry's law constant is calculated to be 0.115 Pa m3/mol at 20°C.
Additional information
The test item does not undergo abiotic degradation (i.e. hydrolysis) in freshwater. Although the test item was not readily biodegradable in an OECD 301F test, simulation studies in natural freshwater-sediment systems show that the test item is not persistent. DT50 values of 25.6 to 30.8 days have been reported for rivers and lakes in China, and a DT50 of 33 days was reported for a groundwater aquifer in Australia under aerobic conditions. Under anaerobic conditions, the DT50 in a groundwater aquifer system ranged from 75 to 85 days, depending on the redox conditions. The test item has low water solubility (1.08 mg/L at 20 °C), low vapour pressure (4.9E-4 Pa at 20°C) and does not volatilise (Henry's law constant: 0.115 Pa m3/mol at 20°C). Consequently, the test item is likely to partition to soil and sediment, having a mean log Koc of 3.70 at 21°C. Although the partition coefficient (log Pow: 5.1 at 23°C) indicates a potential for bioaccumulation, a maximum BCF value of 801 L/kg was reported based on the peak concentration (at Day 14) of test item in mussels during the uptake period (30 days).
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.
