Description of key information

After evaporation or exposure to air, the substance will be slowly degraded by photochemical processes.

Key value for chemical safety assessment

Half-life in air:
1 d

Additional information

Based on a calculation according to AOPWIN v1.92, the substance is indirectly photodegraded by reaction with hydroxyl radicals in the atmosphere with a half-life (t1/2) of about 35.6 hours taking into account a 24-h day and a mean OH radical concentration of 0.5E06 radicals/cm³. The calculated rate constant is 10.8290 E-12 cm³/molecule-sec [BASF AG, 2008].
