Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

Phototransformation in air

Description of key information
No experimental data on the photo-transformation of the substance in air are available. Based on estimation with the QSAR model AopWin, the substance undergoes rapid degradation in air after reaction with hydroxyl radicals and ozone. The half-life after reaction with hydroxyl radicals is 0.045 days (rate constant is 237.6 E-12 cm3/molecule-sec). For reaction with Ozone, the atmospheric half-life is 0.013 days (rate constant is 87.2 E-17 cm3/molecule-sec). These values are not used in the risk characterisation because these are not experimental values. However the data indicates that the atmospheric lifetime of the substance is sufficiently short that it will not undergo long-range transport to any significant extent.

Additional information
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.
