Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Stability
Since the chemical structure of the substance does not contain hydrolysable functional groups, no study on hydrolysis has to be conducted as the substance is considered to be stable in contact with water.
Biodegradation
The substance was determined to be inherently, ultimately biodegradable in a study conducted according to OECD 302 C.
Transport and distribution
Adsorption / desorption
A mean log Koc of 4.63 with a corresponding KOC of 134561 L/kg was calculated by two individual QSAR approaches indicating a high potential for adsorption to soil and sediment particles.
Henry's Law constant
The substance is expected to be moderately volatile as the Henry's Law constant was calculated to be 13.39 Pa m³/mol.
Additional information
The substance is characterized by low water solubility (0.13 mg/L), a low vapour pressure (0.0073 Pa), a moderate potential for evaporation from water bodies to the atmosphere (Henry´s Law Constant = 13.39 Pa m³/mol), a high log Kow (7.77), and a high log Koc (4.63). The log Koc indicates a high adsorption potential to sediment and soil, which can be expected to be the main compartment for environmental distribution.
Based on the result from a standard biodegradation study, the substance is inherently, ultimately biodegradable (79% within 28 d, OECD 302 C). Abiotic degradation in water is not a relevant degradation pathway, since the chemical structure of the substance does not contain hydrolysable functional groups.
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.
