Description of key information

Calculations with AOPWIN showed that the half-lifes for the substance are 0.175 days (2.097 hours) in reaction with hydroxyl radicals and 0.336 days (8.060 hours) in reaction with ozone.

Key value for chemical safety assessment

Half-life in air:
0.175 d

Additional information

Calculations were performed with AOPWIN v1.92 (EPI Suite, 2008). In reaction with hydroxyl radicals, the half-life of the substance was found to be 0.175 days (2.097 hours) at 25°C with 12h-day and 1.5 x 106 The overall OH rate constant was 61.21 x 10-12 cm3/molecule -sec. In reaction with ozone, the half-life of the substance is 0.336 days (8.060 hours) at 25°C and 7x 1011 mol/cm3. The overall ozone rate constant is 3.412500 x 10-17 cm3/molecule-sec.
