Description of key information

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

Key value for chemical safety assessment

Half-life in air:
1.85 d

Additional information

Based on the calculation according to SRC AOP v1.92, the test substance is indirectly photodegraded by reaction with hydroxyl radicals in the atmosphere with a half-life (t1/2) of about 1.85 days taking into account a 24-h day and a mean OH radical concentration of 5.0E+05 radicals per cm³ (BASF 2007).
