Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Stability
Phototransformation in air
Degradation rates for gas-phase reactions of the test substance with hydroxyl radicals and ozone in the atmosphere were calculated using the AOPWIN program, v1.92. (EPISuite v4.11).
The calculated degradation rate of the test substance with hydroxyl radicals (OH) is 57.8392 E-12 cm3/molecules/s and with ozone 0.875000 E-17 cm3/molecule/sec. The atmospheric degradation half-life of the test substance due to reactions with OH radicals is 2.219 hours (24 hour day). The atmospheric degradation half-life of the test substance due to reactions with ozone is 31.433 hours (24 hour day).
Hydrolysis
According to Kollig et al. (1993), Boethling & Mackay (2000) and Harris (1990), the test substance is generally resistant to hydrolysis because it does not contain any labile functional groups. Therefore, no study on hydrolysis is performed.
Biodegradation in water
A valid, guideline-conform CO2 evolution study according to OECD 310 B was conducted under GLP. A biodegradation degree of 50-60 % CO2/ThCO2 was observed after an exposure period of 28 days. The test substance therefore was not readily but inherently biodegradable under the conditions of this test.
Transport and distribution
Adsorption/ desorption
Following Koc QSAR data have been derived from EPI Suite: First Order Molecular Connectivity Index log Koc = 3.59, log Kow method log Koc = 4.05. According to the mobility classification developed by FAO and recommended for use in EFED when it is appropriate to describe the compound's sorption using KOC values (FAO, 2000; USEPA, 2006), substances with a log Koc at around 4.0 are classified as slightly to hardly mobile. All available evidence therefore suggests that the substance is slightly to hardly adsorbing to particulate matter in the environment. As worst case assumption, the higher of the two values obtained by QSAR computation of log Koc = 4.05 shall be used for chemical risk assessment.
Henrys Law Constant
The Henry's Law constant was calculated using SRC HENTYWIN v3.20. The calculated constant is 13100 at 25°C. However the substance is not within the applicability of the model.
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).
