Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Stability of the substance in the atmosphere was calculated using the software AOPWIN (v 1.92). It is predicted that the substance will be degraded in the atmosphere by reaction with photochemically-produced hydroxyl radicals. The half-life for this reaction in air is estimated to be approximately 4.3 hours.
The stability of the substance against hydrolysis in aqueous media cannot be predicted.
Biodegradation
A number of tests of ready biodegradability have been undertaken either with the substance itself or structural analogues. The results obtained demonstrate ready biodegradability. In addition, the potential for the substance to be readily biodegradable has been calculated using the software BIOWIN v4.10 and the results indicate that the substance is expected to be readily biodegradable.
Simulation tests of biodegradation in water and sediment have not been conducted as the substance can be regarded as readily biodegradable.
Bioaccumulation
The potential for bioaccumulation of the substance is low - Estimated BCF equal to 70.8 L/kg whole body w.w.
Transport and distribution
Adsorption/desorption - Koc was calculated using the computer program KOCWIN (v2.00). It is predicted that the substance has a Koc of 8860 L/Kg.
Henry's Law Constant - The Henry's Law constant was estimated using the software HENRYWIN (v3.20). The value of 2.75E-6 Pa m³/mol indicates that the substance is not significantly volatile from surface water.
Distribution modelling - Distribution in environmental compartments has been calculated using a Fugacity model according to Mackay, Level III. Soil and water were found to be the major target compartments.
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.
