Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 of analogs of the substance in the atmosphere was calculated using the software AOPWIN (v 1.92) as the substance itself was recognised by the software. The analogs examined were predicted to be degraded in the atmosphere by reaction with photochemically-produced hydroxyl radicals. The half-life for this reaction in air ranged from 0.5 hours to 4.3 hours with an average of approximately 2.2 hours.
The rate of hydrolysis of analogs of the substance in aqueous media has been estimated using QSAR methods, the substance itself not being recognised by the software used. Half-lives of 1 to 1.7 years (average 1.35 years) at pH7 and 36.47 to 62.35 days (average 50 days) at pH 8 are predicted.
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.
