Description of key information

No experimental data on the phototransformation of the substance in air are available. Based on estimation with the QSAR model AopWin (v1.92), in air the substance undergoes rapid degradation after reaction with hydroxyl radicals and with ozone. The DT50-value after reaction with hydroxyl radicals and ozone is 1.11 hours and 38.4 minutes respectively. This indicates that the substance is not a long-range transported chemical in air according to the UNECE criteria (http://www.unece.org/fileadmin/DAM/env/documents/2000/ece/eb/ece%20eb%20air.60.e.pdf). These half-lives will not be used for the CSA because these are calculated and not experimental values.
