Description of key information

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

Key value for chemical safety assessment

Half-life in air:
4.8 h

Additional information

Based on a calculation according to AOPWIN v1.92, the test substance is indirectly photodegraded by reaction with hydroxyl radicals in the atmosphere with a half-life (t1/2) of about 4.08 hours taking into account a 24-h day and a mean OH radical concentration of 0.5E06 radicals per cm³ [BASF SE, 2008].
