Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Hydrolysis
The hydrolysis of the test substance was tested according to OECD guideline 111. A pre-test was conducted demonstrating that the substance is stable at pH 4 and 50°C. The main test was conducted at 25°C, at pH 7 and pH 9. DT50 values were 110 h and 38 h, at pH 7 and 9, respectively.
Biodegradation
The substance was found to be inherently biodegradable in an OECD 301F test (42% biodegradation by activated sludge after 28 days ). In addition, the biotic degradation products were identified and quantified via the QSAR CATALOGIC 301C Model v.11.15.
No further testing on biodegradation in water, sediment and soils is considered necessary.
Adsorption/desorption
Under the test conditions, the chromatogram of the test substance resulted in four peaks with log Koc values of 1.422 ± 0.001 (peak 1: 0.690 mAU*min), 1.812 ± 0.003 (peak 2: 0.268 mAU*min), 2.605 ± 0.001 (peak 3: 7.750 mAU*min) and 3.550 ± 0.002 (peak 4: 20.058 mAU*min) at 25 ± 1 ºC.
Henry's law constant
The Henry's constant of the substance is estimated at less than 0.00000512 Pa m³/mol.
Bioaccumulation
No bioaccumulation was observed in fish in a test performed according to the OECD 305 testing guideline.
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.
