Description of key information

Based on estimation with the QSAR model Aopwin the substance undergoes in air rapid degradation after reaction with hydroxyl radicals or ozone . The DT50 values after reaction with hydroxyl radicals is 3.3 hours The DT50 values after reaction with ozone could not be calculated. The estimated half-life time is much shorter than 2 days, which is the cut off time for reaching the stratosphere. The substance is therefore not expected to reach the stratosphere and 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). 
In addition, the substance does not have an ozone depletion potential, because it does not contain halogens and does not have the potential to reach the stratosphere (CLP, 2014, Part 5 (page 203),

Key value for chemical safety assessment
